Because native russian speakers don't have the perspective of learning it as a second language. Of course everything we learn as kids looks more obvious later on. I think the Russian cursive is at least one level above of complexity compared to at least neolatin languages (like Italian, French, etc.). I don't know about German though.
Also, it might be a matter of familiarity in general. All Russian speakers I have known could always read Latin characters, so the alphabet is probably generally more familiar to most people compared to Greek or Cyrillic alphabet.
There is no need to compare bigoted religions. However, if you want to do so Islam comes out as the more bigot and violent hands down. Look at the punishment for apostasy or homosexuality as an example.
Sure, it is a minority religion in the west, thankfully, so it is less of a problem compared to Christianity from a selfish, west centric view. However from a general perspective of how religion is used to oppress and control other people Islam is pretty much where Christianity was 3 centuries ago.
Yes, many people hate Islam because they want their bigoted religion not to be threatened, or because Islam is practiced by people too brown for their racism, but this doesn't mean that every time someone criticizes Islam for the many, many reasons that it deserves to be criticized, people need to jump to defend it.
What is even more shocking is that this regularly happens in communities where using the wrong pronoun is considered a capital sin, but somehow defending a bigoted religion that in some cases leads to the hanging of homosexuals is fine, as long as it's a reflex to other bigotry (real or perceived).
