First off, thank you.
As for the rest...it's just a meme. This particular one wasn't about suicide bombers, so much as it is about generalizing Muslims and their love affair with blowing things up. Yes, it's bad to generalize, but it's 2016. C'mon, man, you know all Muslims are terrorists, all white people are racist, all blacks are lazy, and all Mexicans like to steal...we know that Trump hates Mexicans, and Hillary hates Americans. We know that all cops like to shoot blacks, and ONLY blacks, and for no reason other than they are black.
You've been here long enough to know that some memes have more edge than others. Remember what Dory says..."Just keep scrollin', just keep scrollin'..."
