As a moderate on reddit I see leaking from both sides, but leaking from r/the_donald is much more contained.

It is particularly annoying when a hobby subreddit gets swarmed by the fanatical social justice crowd and kills all conversatamd community that existed previously.

The leaked content from r/the_donald are downvoted to oblivion. The leaked contentent from r/shitredditsays has much more power.

However, if you are simply seeing conservatives from r/news posting, and assuming they are crazies from r/the_donald, then you are assuming bad intent and may need to re evaluate how many conservatives live on the internet. Regardless of your political affiliation, you will see opinions you disagree with and that’s a good thing for the most part.
