You just need to find smaller subreddits, obviously in the big ones anything going against official leftist/progressive opinion is banned, deleted or downvoted into oblivion (HN is only slightly better in this aspect, but I would say there are smaller subs which are more open minded than HN)

I wish there was no downvote feature here and you could flag anything publically only with publically stating reason for flag without abusing this feature anonymously.
