As far as racism goes, not once have I experienced any sort of derogatory discrimination thrown at me, atleast in the comp community. (Shoutouts to ALL the french people I have ever met, all of which have been the kindest to me wherever I interact with them!)
Now, even though it's not explicitly stated in the question, concerning transphobia - I have come across individuals who have been actively transphobic towards friends and non-friends of mine, so there is still an issue there.
People need to control what they say, understand others more and just make sure they give others a fun time to enjoy playing video games - one day...
