Then don't bring irrelevant facts to the conversation if you are not willing to defend their relevance.
No, not every group has a political overlap, and there are different degrees of overlap.
Please name a major non-profit group that has never been used in political discourse. Please spell out how you can know this degree beforehand.
Also, You did not answer the questions that I asked.
I think I did, but I will endeavor to answer them more directly for you.
Are you sure that their lower tax ads don't align with political agendas?
I'm sure lower tax ads align with political agendas, just like ads from the American Cancer Society (ACS), the ASPCA, and pretty much every other group align with political agendas. It we prevented any group whose mission aligned with some political agenda from having non-profit status, there would be no non-profit groups.
Are you sure that they are not really persuing a political agenda and using the tax issue as a cover?
You can have a political agenda as part of a larger social welfare concern. The ACS wants to spend more money on research, which is a political agenda.
Are you sure that they spend under 50% on nonpolitical ads?
This question makes no sense. If you don't allow them to engage in fund-raising on a non-profit basis, then they can't spend on anything. Is $0 more or less than 50% or $0, to you?
If they spend 45% on political ads, and another group spends 0% on political ads, doesn't it make sense to spend time taking a closer look at the app with the 45% political expenditure?
Again, this question assumes they are already spending, when the IRS is holding up their non-profit status, thus preventing them from having money to spend.
