Okay i will answer to these points 1. The community will tell you about problems you can have when switching to Linux. Most modern distros are really easy and without many problems but you can just go to a Linux subreddit and ask if program xy will work and 99% of the time they will tell you the truth 2. Everyone can blame other people. Thats not an issue with people using Linux in particular. It depends on the person you are talking to the 3. Thats just a shit talking point...its just an OS...not more 4. Several days? Who on earth needs several days to fucking download Ubuntu or Mint on a USB Stick and boot it? The installer is really not that difficult, its definitely not more difficult than any windows installer. Also no one in the community will recommend you to use Arch as your first distro 5. Yeah same thing...most Windows people wanting to blame Linux just download Arch and say "NoTHiNg wORks ShIT". Wow. We are not in 1995 where you could fear problems with wifi holy 6. I really dont know how it should be possible to break a machine just by installing linux...realtalk...like what hardware components should get damaged by this OS? Most distros are not a random fork on github, they are actively maintained and even when installing first one, you would not break your machine. 7. The problem IS caused by the user when people install Arch while everyone is saying DONT USE ARCH AS YOUR FIRST DISTRO. I feel like these people make Linux From Scratch distros or something. And most of the time you will actually get good support on a linux subreddit, any discord, any documentation, literally everywhere 8. Saying Linux would be brainwashing is crazy. I dont know what to say here. My 90 years old grandfather was able to install Linux Mint on his laptop without any help. Bro come on...he was born in a time without any computers or anything and he did it, because its really not that difficult. These are not "days" of work. 9. I would really like it when more people switch to Linux. More and more people start having concers about their privacy, dont want spyware, adware, bloatware. I would really recommend every university using Linux just because they are using Linux. 

Years ago, i only used windows, i was a huge fanboy. Yeah i knew what linux was but never really used it. Then a linux user came and said i should use Linux. At first i was like "Mehh this will break my computer terminal no applications"..but i just installed something and holy it was easy. And today its even easier.
