More absurd false equivalence.

Simply treating a customer the same as other customers is not equivalent to actively providing resources to a political cause.

And yes, payment processors do owe it to customers to treat them equally with regards to their politics and beliefs (as well as their race, gender, language, and so on).

You seem to want to live in a world where wrongthinkers are viciously persecuted by every person, every business, everyone in every possible way. Because you think you'll always be in the team with the power to do that. When you have the experience of being the hated minority, you'll understand the value of equal treatment and the norms of individual freedom.
