Homo and arhiesm are different topics.
why should they be related??

I don't think it's the laws, it's more about how churches with negative messages (you'll be punished if you don't do this) are having a tough time attracting new people and/or keeping the old ones, so many churches prefer to use positive messages to bring people in and keep the ones that are there.

Here, the catholic church used to be very controlling and threatened people with Hell and stuff, to a point where the people got totally pissed off and threw the church out of everything they had an hand into before - education, health, orphanages, government. I think they learned their lessons and don't want that to happen again anywhere.

In Islamic countries it is the opposite. They are ok with an Atheist as they believe that it can be just a phase.

I've seen young people on other message boards explain what it was like when they came out to their very religious parents that they were gay.
Many said their parents told them that they were so worried their child was going to say they were an atheist, they were relieved to find out they were only gay.

As a gay man, my personal experience is that atheists are far more accepting of gay people than religious persons. There are some atheists who carry dogmas that ori9ginated with religion. Although they may be more outspoken, they do not represent atheists in general.

Most religions that do somewhat accept gays, do so conditionally. In that you can be gay as long as you never act on your sexual attractions or feelings. That isn't really actual acceptance. It is more an accommodation of scientific views that sexual orientation is fixed at birth, and a way of perpetuating belief in the face of direct contradiction to church doctrines. In short the conditional acceptance is an adopted dogmas to perpetuate existing beliefs.

Because disbelief is the only unforgivable sin in the Bible. Everything else can be repented.

As Christian religions began to lose more and more of their congregation they have had to make some concessions to the hard and fast rules they imposed. By relaxing the rules they hope to attract the younger generation.

Many churches will welcome non-believers as long as the non-believer will listen and not try to convert their members.

When something becomes acceptable in society then religions will usually back off their rhetoric. The bible thumpers are a different story.

I do not believe so. I believe that some Christian sects are more liberal and see the LGBT person as someone who believes in their God, unlike atheists who do not believe in any supernatural being. A small number of Christians still believe that homosexuality is an ailment, but do not see their rejection of atheists as a "hate crime" but recognition of their "extreme disbelief." If a person whats to persecute atheists, they will despite the laws of the nation. Some believe that the laws of the Bible outweigh the laws of man, though the Bible does not mention homosexuality directly.
