atheist do you agree love is love?

Not believing in a god has no correlation with physical attraction. Idgaf who marries who, as long if they are the age of consent or over it in their local jurisdictions.

Love is many things, most of it unrelated to sex.

Having said that, I have zero desire to be the boss of your genitals.

Yes.

The age of consent is 16 not 18 in most civilised countries. That means that although they are not adult, 16 year olds can have a sex life without being bothered by the law or god-botherers. If people in love want to have sex, who am I to stop them? I would make sure that all young people had a good sex education and that they were given easy and free access to contraception. We could cut the abortion rate dramatically if this was the case.

i'm not going to tell people what consenting adults can or can't do in the bedroom

yes jesus and his disciples were all doing it with each other at 18

Atheists know, agree, and understand that "Love" is many things.

Yes.

Why wouldn't it be.

But if you're talking about marriage....then thats different. Marriage is about sacrifice - a much higher and very different form of love. You'll see when you get there.

If you're asking about what actually CAUSES love....

Love is directly observable as a neurochemical process in the brain. It is an emotional response caused by a whole bunch of chemicals like oxytocin, dopamine, adrenaline, serotonin and glutamate and their combined effect in certain regions of the brain such as the anterior cingulate and hippocampus, which triggers the complex feelings called love.

Alter the chemicals around a little differently, and you get the same feeling as a drug addiction. Alter them again, and you could have the same feeling as a child predator.

Neutralize those chemicals with a blocker like an SSRI, and you lose the feeling of love for your lover.

Love is a specific type of emotional response to a very specific combination of neurotransmitters in the same parts of the brain that can cause drug addictions or sexual fetishes if the levels of neurotransmitters are disproportioned.

Who cares what they think.. they'll croak twice if they don't repent

Love has nothing to do with a belief in a silly god. Dipshit.
