This was my experience as well. Definite targetting. Most of the bans coming after being critical of Capitalism. The Reddit incels and rightoids like to whinge that Reddit is anti-right wing and moderates those viewpoints into oblivion, but it's just cognitive dissonance or gaslighting. You can do just about anything short of direct threats or doxxing on Reddit and be just fine, as long as you don't question that which is unquestionable, i.e. Capitalism. Even inside some very socialist or left-leaning subreddits you see this.
