Sure, everyone has some. I probably have some too - I don't keep track of them, but I know mocking some of the things that I hold dear will definitely unsettle me.

That said, one of the core part of growing up, of becoming an adult, is learning not to get triggered, and in the rare cases you still are, learning to calm yourself down. It's a prerequisite for participating in and contributing to a healthy society.

Nobody could possibly keep track of the list of trigger words for everyone they could come into contact with. The list itself would cover so many phrases across so many topics as to prevent communication. Even if we could keep track of all of this (scary thought: for the first time in history, this may become possible, thanks to computers), erring on the side of avoiding any and all trigger words would be a security vulnerability, easily abused by people trying to gain power over others (arguably, the very list we're discussing is an example of this).

The point is, we can make some concessions for words or phrases that are intended to harm or known to negatively affect a lot of people - which is what cultures have been doing throughout the recorded history. Beyond those few concessions, it's up to individual to handle their own triggers, in a way that doesn't disturb everyone else's ability to communicate effectively.
