I am not a muslim apologist. Quite a leap there, buddy. If it was a terrorist attack, then, yes, consider the religion. But this was a domestic murder-suicide that had nothing to do with religion. If you think it does then you, by your same logic, better examine what it is about christianity that prompts so many similar crimes amongst them. Christians are murdering others constantly in this country. What is it about Christianity that causes that?
The answer is, nothing. Nothing about Christianity prompts this just like nothing about islam promted what happened in this case.
It’s embarrassing for our side to immediately jump on the Muslim angle when the behavior is far more typical of a U.S. citizen who happens to be Christian.
Save your fire for times when Islam really does play a role and your opinion will be taken more seriously.
This was a standard, run of the mill honor killing, and no, the Amish and the Methodists don't react that way.
Contrary to your personal Muslim apologetics campaign, honor killings are a Muslim problem and Islam is indeed a religion.
