Who is ‘they’? I’ve been an open atheist for 45 years, and I do not perceive any threats from ‘them’, whoever they are. I have LGBT friends in the U.S. and Canada, and none have been threatened because of their gender or sexual orientation.
Madelaine Murray O’Hair was an athiest activist all her life, as was Ayn Rand. No one went after them, and the US was a lot more religious then. Many on the right loved Rand, and didn’t give a rat’s ass about her strident atheism.
Worrying about religious mobs going after atheists is paranoia, and not reasonable. At least not in America.
If you are worried about Republicans gaining power and using it to go after you, then what you should be doing while you are in power is strengthening institutions against censorship, prosecuting officials who abuse their offices to punish political opponents, upholding the law against riots and genral lawbreaking, and upholding filibusters and other rules that make it hard for a small majority to impose sweeping changes on the nation. Because one day you will be in that minority again, and you won’t like it when the rules you created are turned on you. As Democrats found out when they got rid of the judicial filibuster, which backfired spectacularly and predictably.
Instead, the attitude seems to be to do the opposite and break all the rules protecting political minorities from the governing majority and public passions, even ones that protected tou, to gain temporary advantage. It’s a bad strategy, and it will eventually cost the Democrats and the country.
The only real problem I can see as an open atheist is that it would be harder to get elected to major office, which is why so many politicians have to proclaim to be faithful church-goers even when it’s clear they are not. It makes America look more religious than it actually is.
Between 1940 and 2000, church membership in the US was stable at around 70%. Since then, church membership has been collapsing and by 2020 was at 47%, the first time non-churchgoers were in the majority.
It looks to me like it’s the religious that should be worried, not the atheists.
