And that would be fine. Christianists never understand that our issue is with government endorsement of a religion, not with the freedom of students to express their beliefs. More power to you on the t-shirts. While you're at it, please coat your lawns with creches. That'll show us! That you've finally learned the difference between using your own property for something and using property that belongs to everyone for it.

Having it on t-shirts is fine, the ACLU has gone to court to defend the rights of students to wear such t-shirts.

So Christian organizations should not be tax exempt?

I don't think 'objecting to me using the government to push my religion is a religion so if you stop me from getting government endorsement for my religion you're getting government endorsement for the religion of non-endorsement' is going to fly with anyone who has at least half a brain.

It's not even a philosophy. It's an opinion on the topic of God's existence, just like theism, which is also neither a religion nor a philosophy.

They shouldn't be taxpayer funded either. The FFRF only goes where they're asked, if the government is funding footbaths at your airport, try reporting it (with details) to the FFRF.

Nonsense. When a public school puts up plaques endorsing the Five Pillars of Islam, complain to the FFRF and they'll be right there.

You're almost there. The FFRF only interferes with Christianists when they try to use government resources to promote their religion or make it appear as if the government endorses their religion. Christianists DON'T have the right to force their religion on other people. Government is force. All the FFRF is doing is keeping people from forcing their religion on others.

You're not God. God isn't using government property to send a message, people are.

There is no right to the use of government resources to promote your religion.

It's not anti-religon. If the school represented more religions on their plaques, they'd be fine. The problem is they're only endorsing Abrahamic religions.
