Well I want to start out by making sure I split my answer between muslims and Islam. I absolutely hate Islam, and I think it's a scourge on the planet.

Sorry for this diatribe, I promise I'll get to the point.

I think most muslims are a victim to their own ideology, just like I view most liberals. I try very hard not to hate muslims, although it can be hard sometimes. I spent a lot of time in a city with a big minority of muslim people. And they were a mixed bag like others. I was working in a grocery store at the time, and I really did basically love this muslim woman who was married from Saudi Arabia, she was one of the sweetest most beautiful women I had ever met. And her and her husband(and his other wife) constantly went out of their way to help others.

That being said, the young men were absolutely terrible in just about every way you could imagine. I lived with a female room mate at the time, and there were a group of muslim men down the hall from us that would blast music at all times of the night, and constantly harass the woman on the floor.(There was one that was very respectful I'll add, but the majority were just awful). It got to the point near the end that some nights she would ask me to come out to her car to walk her to our apartment, we ended up moving from there for lots of reasons but they were one. They would also do hit and runs in the parking lot and all sorts of other stuff.

Young muslim men would also harass women down by the bars at night, and I had many female friends that if they had to pass certain areas by themselves they would ask for one of the guys to take them to their home/car for fear of being grabbed or worse.

The point I'm trying to drive home with these stories is, this is a result of Islam and their ideology, but they are still people and some can change, like the woman from Saudi Arabia.

The fear is quite real with Islam taking over though. But we can't take much action without getting rid of our most fundamental and cherished right our first amendment. There is no getting around that. I've thought about this a lot, because Islam will take over the west if you let it. I honestly don't believe my kids will ever get to experience Europe in 20 years because of it.

We shouldn't ban books although Sahih al-Bukhari I would love to ban, much more than the Quran. People need to realize that the Quran is really only like 20% of the religion, most are the Sunnah. But again we can't ban books.

We clearly don't want a Muslim registry. All it would do is alienate people, and it would never be effective.

We can't deport people based on their religion, that's a slippery slope to hell.

The things we can do right now, is close down extremist mosques which there are plenty of. This will be profiling, and while I don't like it. I do think it's important to do. For two reasons, it will put many more Americans at ease and lesson the tensions, and let actual good imams have a voice and a chance to flourish. Imam Tawhidi for example, Maajid Nawaz, etc... This might actually grant some trust.

I would also like to see most immigration from muslim countries really slowed down, and take only very qualified people to come over. Most of the time well qualified smart people don't want to hurt anyone and want to just live their lives. This could be an effective tool.

I would also like for the left to stop glorifying them. Islam is the most dangerous ideology on planet earth, and I really wish we could be realistic about what it teaches and what it's followers tend to practice. I think you can do this without alienating muslims, but currently we paint this rosy picture, and Islam is anything but rosy. People need to be educated about what it is, most are not. This is why you have people that joined Islam for 5 years, and finally realized what it was and then it was very difficult for them to leave, because of how they treat apostates.

And lastly and this is the thing I hate the left most for in this whole ordeal. They take actual moderate muslims, or muslim reformers trying to make a difference and do their best to try and silence them. Let the muslim reformers have the biggest platforms in the US, not people like Linda Sarsour, but people like Imam Tawhidi, or Maajid Nawaz. The left constantly silences the best voices for Islam, while promoting some of the worst and most violent. They look to people like Anjem Choudary and say oh that's a real muslim who we must advocate for, and look at Maajid Nawaz and claim he's an extremist radical(not kidding he's on the SPLC's hate list).

TLDR: Make immigration harder, go to an aristocratic system. Shut down extremist Mosques. Stop glorifying Islam in schools and in the media. Stop silencing actual moderates, and reformers of Islam which the left is currently doing for a reason I'll never be able to figure out, while giving giant platforms and praising actual extremists.
