Well, feminism is about gender equality from a very specific perspective on society, namely one that assumes the existence of patriarchy. You don't need to demonize feminism as inherently anti-male to disagree with that concept and thus disagree with feminism's focus or some of the contemporary rhetoric that seems to accompany it. Likewise you don't need to worry about things like 'cultural appropriation' to be anti-racist.

It's all well and good if you disagree with people's opinions on whatever, but it's disingenuous to decide that because someone thinks something you don't feel is very liberal they're suddenly a secret conservative even though they're life-long democrats who've always supported liberal causes.

You may remember that back in the 90s it was liberals who were defending art and media that was under fire from religious conservatives. That the same sort of hypercritical attitude is coming from left-wing authoritarians rather than right-wing authoritarians doesn't suddenly push those who oppose it to the right.

Again, the question here is how much evidence exists that reddit is leaning to the right. Pointing out redditors who oppose authoritarian positions isn't the same as pointing out conservatives.
