Black people get their own day/month long holidays because they were oppressed and treated like slaves, why shouldn't any other groups of oppressed people get holidays to welcome them and make them feel more accepted among society?
If you need a month dedicated to you to feel accepted, you might be a narcissus. Pride is a sin for a reason; not to get biblical here, but look at the principle. One of many stuffty human traits to have, let alone be proud of and own. Not that I'm religiously inclined, but it's fair to say that the 7 deadly sins are basically a list of stuffty traits you should control/keep in check, not be loving proud of them lol
