so is it unfair to say a community that mostly upvotes plain xenophobic comments has an issue?
and it's not from now -- i've been here for a while and every single time h1b is mentioned, there are upvoted comments saying weird stuff that is never removed.
That's far from the case. You might be running into the notice/dislike bias, which unfortunately tends to distort perceptions and leads to false feelings of generality.
