They were not mean tweets to anyone that wasn't told to be triggered. That is what the trigger warning is. the switch to the trigger or else they wouldn't know they are supposed to take offence. Must be one hell of an existence to be totally controlled by social media.
I have better things to do than worry about someone's opinion of what I should be upset about. I can think for myself. Reall a sad state that so many are incapable of self expression.
