How is it totally legal to commit adultery in the western world?

@AgapeLove

I agree that being gay is not wrong. But the connection is in the idea that the government should have the power to legally punish you if they don't like what kind of relationship you have.

I mentioned the fact that having a gay relationship could be punishable by law in order to demonstrate what dangerous concession it is to give a government that much power over the personal lives of its citizens.

@AgapeLove

The government should be able to punish two consenting adults if they don't have a relationship of which the government approves?

Wrong.

@AgapeLove

Free and willing consent is the exercise of our most fundamental right: the right to bodily autonomy.
What reason can you think of that consent should not be the benchmark for where we draw the line?

Your right to swing your fist ends at my nose.
That is to say, your rights only stand until they infringe upon the rights of another.
Discrimination based upon things like gender or religion is something that we've decided (at least officially) are unacceptable.

Even when married, you don't have the right to another person. They are not yours and they can continue to act autonomously. If their choices are incompatible with your desires (for instance they want to fuck other women) then the relationship cannot continue.
It's a shitty thing to do but keeping legislation out of adult relationships is something everyone agrees is important.
We can't cherry pick
