I no longer really believe the French Revolution was anti-Christian. Yes, they executed priests en masse, raped nuns, burned down churches, shut down churches, blasted church stained glass windows with cannonballs, banned Christianity, subordinated the Church to the state via the Civil Constitution of the Clergy, melted down church silver for money to pay for their wars, confiscated church property etc. But these things were done because the church was an independent power that could have challenged the new state, not because they were opposed ideologically to Christianity (though many of them were). The radical atheist Hébertists were also all executed. It would be stupid to claim the Revolution was oppressing atheists, it was all purely political. You got purged if you stood in the way of the new power, it just so happened that religious types (as well as royalists) were more willing to fight back, and as a result they all got crushed. Sieyès and Tallyrand were both clergymen and at no point did they ever feel the need to renounce their faith or connection with the church during the entire time they were part of events. Also Robespierre hated atheism.
