Looking at a company's background

Assalamualaikum Warahmatullah.

I wanted to confirm on whether it is allowed to invest in a company that openly supports lgqbtq. I was invested in a company for a while and I just noticed that they have a section on their webpage supporting the lgbtq movement. From an islamic standpoint is it allowed for me to be invested in these companies or should I sell it and invest in companies that don’t openly support it. If I do need to sell it do I need to do purification on the capital gains?
