I've been subscribed to /r/canada for as long as I've been on Reddit but it's now it's become a right-wing hate fest over there. I'm surprised at the decline in the last year or so.
I was blown away to watch the transformation happen first hand. I can't even go there anymore, it's become so incredibly toxic.
There's a concerted effort by right-wingers to overrun every "local" reddit. If you go to /r/seattle or /r/seattlewa half the comments in most posts are HEAVILY downvoted hate speech and trolling.
It's natural for /r/Canada to go against the government of the day. Just like they loathed Harper, so too will they loathe Trudeau. That's just the burden of governing.
