You need better mental health care.

you start off by saying you’ve always thought you’re on the left

but the moment you disagree with someone, you start shit like this, which is a very common pattern of argument from right-wingers.

“I think your opinion is so wrong that it’s a symptom of mental illness” is just fucking stupid. do better. or, if you refuse to do better, stop attempting the “I’ve always been on the left but…” shtick. it is absolutely see-through and does not fool anyone.
