SR is far from being mainstream and unfortunately a taboo topic

So from my own experience on Reddit I can conclude that SR is not in the slightest mainstream. Galaxies away from being it.

This happened to me several times already. And just today again. So I wrote a comment with a rather unpopular opinion in another sub absolutely unrelated to SR also never mentioning anything about SR. The problem is not that I got down voted for it. The problem was that the only two comments that answered were 2 ad hominems referring to me having several posts on the semenretention subreddit. Totally unrelated to the topic. Moreover they were getting up voted for it.

So relating someone with this topic destroys that someone's reputation. It's sad but seems to be true. That happened several times in the past already. Have you had similar experiences on this topic? And if so, how do you deal with it?
