Never understood how much space I can take up in someones head until someone posted something random that was my personal opinion from a year ago and is holding it against me.
With due respect, you dropping into a random thread to crap on someone instead of defending yourself in that thread is telling. The conversation was civil. It's a normal thing to remember someone's positions, especially someone as memorable as you (this is not a criticism, aderabe). If you change your opinion, that's OK, just say so.
If you take up extreme positions, you best be able to back them up. As an outsider who hasn't argued that topic with you, you haven't. I've been "torn apart" (civilly) by the same group when I've made Covid claims. If you can't handle the heat, stay out of the kitchen.
