The issue is free speech vs. hatred and incite to violence speech. Does a mod, impose his beliefs, and limit someones free speech? That is the question for all.
The answer depends on each person.
There are some that if they disagree immediately with what you are thinking, they delete you and band you. Just because.
In our world, you have a multitude of views, ideas and liberal vs. conservatives vs. extremes vs. communism.
So how do I try to handle it. Being a Jew, more conservative than others, and Republicans, I am in the minority of many. But I also know that debating, discussing and talking about issues, you will always have heated discussions. Free speech is one thing, but speech to incite violence needs to go. If you debate in a reasonable thought process, that is fine, hence free speech, but if you decide to put up a pictures of someone trying to kill someone else (whatever race or religion), or saying 'All Jews or Muslims or Christians Must Die', that is blatant violence speech, and not tolerated.
Resorting to violence, and killing innocents people is just crap. You are a fucking big hero because you shot and killed people who are there just because they are of a race, a gender, a color. Pathetic. You may not like migrants, or illegal immigrants or Jews or Muslims or whatever, but inciting to violence is screwed up, and no, we do not tolerate that.
Yes, I allow debates of all form, that is the true nature of a Democratic site, but I always find it sad that some people think that 'All Jews' or 'All Muslims' or 'All Anything' are the root of their miserable misery. Easy to blame it on someone else when you have to see that usually, it is you that is the problem.
Big ass pathetic creature of mental fuck up shooting and killing a 97 year old. Wow. And yes, I am truly for the death penalty, no mercy for this type of person.
My post was shoah'd within two minutes. 
And you had a point of free speech debates - whether what hate speech leads to violence or just more debates. Just not the right time for those type of pictures at this moment, with 11 killed, and mourning still around.
