First and foremost, I would like to make it clear that, to the best of my knowledge, you were not discriminated against on any basis when you posted How can I prove Google Chrome Webstore that I'm a developer and not a spammer? at Pro Webmasters.
As other answers here have stated, your question did not fit the guidelines applied by community moderation teams.
I am disappointed that you view the actions (to include my own) taken as part of moderating these sites in accordance with the guidelines set forth by the community as being racially (or politically) motivated.
We are here to help others, and (though I do not have an answer that would help you) I think you could find the answer you seek by visiting one of the many StackExchange chats (in particular, ProgrammersProgrammers) where programmers like yourself discuss topics which are not necessarily on-topic for traditional community Question and Answer pairings.
