This is something I've been kinda bewildered to see in the wild, especially amongst MLs circles. Like, surely a tremendous amount of people were Liberal before coming across some solid Anarchist stuff which made too much sense to ignore?

Speaking for myself, I certainly didn't start out Anarchist. It took a long path going from following my religious parent's ideas and traditional values, to questioning religion and becoming atheist, to investigating political ideas, where I came across right-wing libertarian concepts which seemed like the best idea at the time.

It wasn't until coming across Chomsky that I ultimately went down the road to Anarchism proper, and finally all the pieces clicked into place.

Nothing wrong with calling things out as liberal as a descriptor and to accurately point out all of its many many downfalls, but could be quite offputting to use as an insult to people reading who consider themselves liberal still.
