The church has even from the first centuries been anti-abortion. Marriage is definitely between a man and a woman, and only sex within marriage is considered moral. Homosexuality is usually a symptom of idolatry, as is recreational drug use.
No, the church doesn't go around telling people they are going to hell for "breaking the rules". That said, the church isn't going to lie to you and tell you that evil is good and that good is evil. The church is there to heal you. There is no force or coercion involved. You do have freewill. And part of having freewill means that you can choose to reject healing and go on sinning in your pride. However, this isn't really beneficial for you, and it isn't always easy to see this when you are being blinded by your affliction. There is a certain trust involved. We see God as our father and the church is our mother.
The church doesn't really tell people they are going to hell. We all pretty much understand that God is the rightful judge of these things.
And we pray for those who persecute us and bless those who curse us. That is at least, the example we are given.
And well, Orthodox Christianity might have been what ended up toppling The Soviet Union, because they had an officially "Scientific Atheist" government, and did everything they could to eradicate God from their country. Millions of martyrs. Christians were second class citizens. They demolished churches, seminaries, slaughtered so many priests, even tried to corrupt the church through infiltration. For 70 years, they did these things to the church. But it didn't work, and it wasn't long after the Soviet Union stopped its persecution that it fell. And good riddance.
And we Orthodox do not believe in revolting against civil authorities. We are innocent, and walk the path of peace. Despite this, you will not find any other church that has been on the receiving end of so much persecution. That is why we are nicknamed the church of martyrs. Over 20 million of us killed in the last century for our beliefs, and despite this, anti-Christian rhetoric is fairly normal. Everytime the heretics do something evil in the name of Christ, we are the ones who seem to get killed for it. Very tragic.
