Stop it. Just stop.
You’re never going to change someone’s mind by scolding them from the comments section, especially the rambling, candy-headed personification of a Forever 21 knock-off. (Honestly, how do you even tolerate ten straight minutes of that shrill twit?)
Don’t waste your time trying to “get her to understand.” She’s made it clear that she doesn’t give a fuck about your politically correct opinions. Let it go.
In fact, you should fuck off completely. (You’re just as insufferable as she is for thinking it’s your place to whine about your personal politics on her cartoonishly trivial YouTube beauty channel.)
We live in a world brimming with ignorance and insensitivity. Learn to pick your fucking battles already.
