But not to JUST that group. You are also providing "material aid" to every other group that uses your service which is what makes it apolitical.

We have a system for resolving political differences in America. It's called elections. There is no reason why every business transaction needs to evaluated on political grounds. In fact tolerance and commerce have historically been key to maintaining a peaceful democracy.

By offering I understand selling it the same way like selling it to everyone else. If by "aid" and by "offering" you mean giving it away as a gift or similar then yes - definitely political.

I see a case where it can be political, like creating a mechanism to protect specific group from the others however simply doing business is not a political action by itself.

There's also possibility to be a political action where it's widespread to deny services to certain groups but even that is a stretch because it can also be a good business opportunity.
