Stop talking about what “Muslims” (as a whole) do.
Your experience, with the couple thousand Muslims you know, your Mosque, your MSA, doesn’t define Muslims.
I’m sorry you had a bad time. I’m sorry they were mean to you. Truly, I hope to be helpful and a resource as you will…
Muhammad bin Abdil-Baqi al-Hanbali:
"The teacher is not allowed to be violent and the student is not allowed to be arrogant."
