I am writing to request that you touch grass. If you are so triggered by a rainbow flag on Reddit that you ask in multiple places for it to go away perhaps you are spending too much time inside. I believe that the subject of a technology mailing list should not be bombarded by your bizarre insecurities about rainbow flags.
I think it would be more appropriate if you simply shut your mouth, without any additional thoughts or feelings. This would make the mailing list more welcoming and tolerable to everybody, regardless of their background or beliefs.
Thank you for your time.
