The generalization is purposeful. There is no reason to generalize; however, when the perpetrator is African American, a Hispanic immigrant, or Muslim, there is always talk of "bad culture" and the responsibility of communities.
Again, you can't keep lumping in racial issues with religious ones...
For one thing, it weakens your argument because one is a circumstance of birth, the other is a circumstance of choice. What's happening to the black & Hispanic communities is grossly more unfair than what's happening with regards to Muslims.
I'll lay out the case again with what's happening with Muslim communities (and again, to preface, judging individuals based on group identities is wrong, I agree with you on that).
The violence being carried out in the name of Islam is happening with greater severity, frequency, and magnitude then what we see out of the Christian world. Sure, you can search the web and find the cases of a radical Christian targeting an abortion clinic...however, show me an instance of where they targeted one and racked up more than 3 casualties...show me the news reports of 4 abortion clinic attacks happening in a 2 month time window, show me the statistics where 68% of Christians say they endorse the attacks?
The reality is,
If "Group A" is responsible for 17 high profile attacks racking up a body count in the thousands over the last 15 years, and
if "Group B" is responsible for a body count between 30-40 across the span of 1982-Present, and the rest is just property damage...
Are you honestly questioning why "Group A" would have a bigger societal stigma than "Group B"? Or do you already, deep-down, know the answer, but wish to blame it purely on bigotry?
For it to be a double standard, both sides being examined need to have equitable numbers... What's wrong with simply telling the truth and saying "Islam has more cultural issues at the moment than Christianity does"?
