It depends on the type of community/communities that you spend your day on as a user there, tbh.
Certain communities in Reddit, usually those centered around science, mathematics, and education are often easier for users to adapt to, as the members there are willing (usually) to be helpful towards users that need help or just want a question answered. Those communities are not bad places for someone who prefers a relatively simple answer to a science question that popped up in his/her head for a moment or two and are too lazy to dig through Google and Wikipedia for it.
On the other hand...
Communities addressing social issues like r/Politics and r/Relationships can be more challenging for those who prefer straightforward expression. Expressing your thoughts in a thread inside these communities pretty much require you to be "civil" for the most part (if you're spouting hard left wing stuff then you got a bit more leeway there).
From spending time lurking in various communities of Reddit, the site itself as a whole, tends to lean left politically, creating an environment that are much more user-friendly if you stand left politically instead of leaning towards the right.
