This is projecting.

Which is a META of your comment

I get you guys hate Pokimane

This is projection, and its based on nothing.

Wouldn't really say I'm invested

You're invested, otherwise, you would just leave and watch someones stream.

you just replying to your comments which come across as a little heated to me

Disagreement and pointing out your hypocricy is all. If you read that in some sort of "angry man" voice, then that is your own head doing that. It's all in text form. No voice chat, buddy.

which I read as your emotional investment in the conversation

That is projection. I write about your hypocricy. There's no "emotional investment" other than your own projection and hypocricy. Are you, perhaps, emotionally invested in my comments?
