I used not to do it and I used to quantify all of my statements until I realized there was an obvious double standard.

I could without problem talk generally about bad about Europeans. Or men. Etc. I wouldn't get tone policed at all.
Statements like "Men are taller than women" wouldn't be corrected even though that's false. You need to add "on average".
Or "Women are better at multitasking than men" wouldn't be corrected.
Even saying "Women are more intelligent than men" wouldn't be corrected most of the time, but would be seen as an edgy joke/comment.

However saying true statement that were negative about migrants or women and you'd get constantly corrected on the language by the very same people that wouldn't mind the exact same negative comments about men or europeans. So I started not quantifying my statements according to leftist standards and it triggered a lot of people, which was fun. It would also allow me to explain to them how they had double standards.

So yes, I don't mind painting with a mighty wide brush as long as people understand what's being said. In our case, we might simply have different labels for left/right. I don't even understand how someone would want to associate themselves with the label "left" when it contains people like the SJWs, antifa, blm etc. In my mind, what you call the "old-Left" is very likely part of what I call the right.
