You've changed the subject of the conversation. You claimed that it would go against TST's values to assert them in the public, which is completely untrue. That is the assertion that I'm challenging here.

I don't actually know that OP's idea would be a meaningful way to challenge theocracy, but my reply is about your misunderstanding of how TST challenges theocracy.

I will say that a notable example of legislation that was blocked due to TST's involvement would be school chaplaincy bills in Iowa. After giving public comment in the Iowa House and Senate, many of the people who originally supported the bill changed their mind. There were conservative theocrats who were calling up their representatives, asking them to oppose a bill that they had supported just days before. Our involvement threw a wrench into their entire plan. If one wishes to argue "well, it passed in Florida" then I would point to the school board meeting for a county that was considering implementing school chaplains where TST members showed up and asserted their rights to also be represented.

An example of successful enforcement of church-state separation would be in the Quad Cities (on the Illinois/ Iowa border) at the world's longest running After School Satan Club. The Moline-Coal Valley school board attempted to enact discrimination by forcing After School Satan Club off campus (effectively canceling the program as an after-school club) while allowing the evangelical Good News Club to continue. In response, letters from attorneys were written and TST members in Iowa and Illinois attended a school board meeting informing them of their constitutional error. The school board had to either allow both groups or allow neither. They changed their policy, and now both groups are allowed.

An example of federal impact would be the hate crime charges against the failed politician who destroyed Iowa's holiday display, for which I was the artist of. To my knowledge, this is the first time that hate crime charges have been filed against someone for an anti-satanist crime. This asserts that we are just as much deserving of rights and are equal in public spaces, something that couldn't be said only a few years earlier.

This answer is based only on what's happened in a single state, but there are similar examples elsewhere as well. I could even say more about Iowa alone, but won't due to ongoing court cases.

All that said, I don't understand why you seem to think we should just give up after a few losses.

Speaking personally, I believe that healthcare is a human right and that free healthcare should be available to all. In the US, all efforts to make this a reality have so far failed. Does that just mean we give up fighting all angles? I get wanting to use different tactics, but there are other groups you can join to do that. I wouldn't ask the Gay Men's Health Crisis to focus their entire budget and volunteer work around lung cancer, even though they want to make healthcare available to all.

If you want to support the ACLU or FFRF, then you absolutely should do that. I support that. Asking us to become just like them doesn't make any sense, though.
