Love and pride are not limited resources. I would say grassroots pride celebration are big and bold because other places won't allow of them. It's celebrating the freedom to express yourself and love who you love openly. One celebration isn't taking away from the lack of another, if anything it's bringing attention to the queer community and how important the right to existence is. Of course it would be ideal for all the corporate overlords to put the money they spend on pride marketing into political action in the countries lacking queer rights but that's not an option we have. It's not like pride is a limited currency we are spending on ourselves and keeping from our oppressed lgbtqa+ community.
