No struggle at all. Religion is easy to despise.

Its effortless for me.

Depends on what you mean by "hate". I don't use that word in the casual way many people will say, "I hate broccoli". I find religion tiresome and annoying, but understand that eradicating it from society and culture is the work of centuries to come, and I'm going to die in a world full of presuppositionalist bullshit. So I don't waste energy on being all up in arms about it, anymore than I waste energy grousing about serialist modern classical music. It's easier to just not listen to it.

I do not hate religion, or religious people. One of my closest friends was an army pastor (catholic himself) and we have discussions on morality, ethics, cricket, rugby, horse riding, cooking - usual discourse between adults apart from sex (taboo for catholics).
The prescence of god at a battle? If soldiers were helped to get through it by believing in a god - I am fine with it. That both sides claim gods support is enough evidence for me to know he does not exist.

I no longer have a struggle with the part that I once believed. I still have a few quibbles with how the believers that I once associated with still behave.

For me personally I find it close to the same feeling I have for my divorce, I'm comfortable with living alone, but wish I didn't have too. Its alot cheaper and easier to handle than divorce, but it follows you around and haunts you at moments of weakness.

Pity the victims, (including all genuine believers) hate the idea. Not complicated, it only gets difficult when some believers use it to expliot or abuse others.

Don't give in to the misinformed so-called believers
