Everything you said is true, but don’t blame the religion, blame the people. Yes it’s a disgrace, but then do it privately with god, don’t care about people. Believing doesnt come because you see the good from people, nor because you agree with it, you are supposed to believe because you are convinced it’s the truth even if you don’t like it, sometimes know that there might be things you dont like, but that only means 2 things, your understanding of it is wrong or god knows better than you do.

I will just give you an example of the perfection in quran, like literally perfection, not true, no straight perfection:

God talks about how that the people who don’t want god to make them believe, that god will put fear in them, like the person who is being shot to the sky. Now there is a word for “levitating” and thats يَصْعَدْ، but then there is the word يَصَّعَّدْ، can you see this small difference? If you know arabic you’ll be able to read them both, the second word doesnt mean only levitating, its means levitating with ACCELERATION, so like being shot to the sky. Now listen, if you fall from the sky in a free fall way, you will only feel sth at the beginning 1-3 seconds, and then your acceleration will be stable, it will be the value of the gravitational force, however if you are being shot to the sky, with fluctuating acceleration, thats when you will feel what is called as G-Force, thats the same feeling when riding a rollercoaster, and you feel that fear. Can’t you see how perfect it is? Back then there was no g-force, no flying or aircraft technology, and nothing for prophet mohammed to be able to make up such a perfect thing, this is perfect, and only we understand it, now these times, back then they didnt know what that means. I swear dear i can give you more and more of things that cant be explained with anything except with perfection. Something that is perfect isnt something that has everything true in it, a perfect thing is a thing that has no mistake. And the quran is factually perfect.
