Reddit can be wonderful.
But the defaults are racists hellholes, look at any thread on Muslims, look at any thread involving black people. The huge number of racist "jokes" that are upvoted, there was a post last week that said black people shouldn't be able to vote, it had 700+ upvotes and gold before it was removed.
Then we have reddit's liberal use of the word fakkit and complete denial that gay people might not like it. This website can be horrible at times but outside of the default subs it's usually full of civil, knowledgeable discussion.
The last survey reddit did showed a 9:1 split of males to females, predominantly white, most subreddit surveys show a huge number of white males as well. That's not a problem but it sure skews opinions towards the whole "white men are the most oppressed group of people" that reddit loves.
Edit:Survey samples just to highlight my point.
/r/Europe-should be equal men and women, men have no reason to sub to
/r/europe over women

/r/soccer-not suprising this is more men, but 97 per cent is a lot

/r/athiesm-again should be a fairly equal split, is actually 80 per cent male

Edit:The useless b*stards at
/r/atheism can't make a survey and only used 100 replies, I am not at all surprised that they are incompetent.
