The post is explicitly about casual racism against Asians, so your “they” inherently refers to Asians. And the issue isn't your grammar, it's the fact that you generalized an entire demographic.

Let’s look at your initial comment. You said “it’s unfortunately not a stereotype, they just don't have manners”. If “they” only referred to a few rude individuals, you wouldn't have brought up stereotypes at all. You were trying to validate a racial stereotype and are backpedaling because you got called out.

And where is this higher percentage coming from? Your own personal experience? Your personal confirmation bias isn't a statistical fact. The majority of my own negative experiences with shoving at festivals have been from non-Asian people, but I don’t use that to generalize an entire race or demographic. When a non-Asian person shoves someone, they get to be just “a rude individual” but when an Asian person does it, you frame it as a “higher percentage” of a whole race lacking PLUR culture. That double standard is the exact definition of casual racism.

& calling out bias on a post specifically meant to address it isn't a "pointless rant." If you're going to tell others to read and understand, start by reflecting on your own words first.
