Re: What would you do?
It's up to you, but I don't go touting my nonrequirement to honour an invisible babysitter in front of my flanders-like cousinry. I treat it as any tradition: it's devoid of meaning to me, just like Christmas, Easter etc, i'll listen to what people have to say, and in return, if I am ever pressured, hope that they respect my viewpoint as much as I have shown repsect for theirs (respect and agreement are mutually exclusive elements in my mind).
Hell, I'm even uncomfortable telling a 15 year old girl, who openly vented her scepticism of the Jesus myth, that I didn't agree with Christianity because of it's values (it's support of homophobia was the example I used), simply because i'm not comfortable broaching the issue in front of other people (there were 2-3 other people in earshot, and my voice carries so well). If someone quotes factual discrepancy however, I choose a path of advice on optional education (putting it lightly)
