Lincoln suspended the citizen's rights to habeas corpus which lawyers that follow the Constitution should object to !I don’t think there is any evidence he’s imprisoned opponents, they’ve jailed some people for taking pro-Russia positions (those aren’t political opponents). Abraham Lincoln did some similar things, most people believe he handled the Civil War well.
The Russian Orthodox Church is in bed with Putin. No one should be surprised Ukraine is treated it skeptically. There’s no general attack on religion at all, the actions of which you complain are directed at a church supportive of Putin.
Ukraine’s existence is at stake and they’ve remained a functioning democracy on things like their conscription bill, which took a long time to pass. Of course they aren’t going to be charitable to people giving aid and comfort to Russia/Putin. There’s always a balance to domestic opposition to wars but usually giving the enemy aid and comfort doesn’t go well for those doing it.
