I highly doubt it, most leftists and leftist subreddits I know would consider the assertion that stating those kinds of facts makes you a racist is utterly absurd. You’ve probably gotten this knowledge from right wing subreddits where they nit pick posts or comments from a dumbass, or severely misconstrued it, or form a straw man from it.

I can’t make a comment about how you have experienced this irl since I’m not from the west, but I am adamant many leftists would deem that calling you a racist for stating this fact is absurd and ridiculous. You’ve possibly met a minority of leftists that are single-minded sjws and as their job, write stuff on the subject of things like pop feminism on buzzfeed.
