I agree with Tom (Tom are you shocked? ) -by so obviously setting yourself apart from the group, the claws are going to come out at you.
If I were you, I would just not get involved in their conversations, even when they asked for an opinion. Just excuse yourself and say you would rather not talk about it.
You sound a little too caught up in all the small details of Orthodoxy, I would talk to your Priest about your many concerns, so you can better concentrate on what is more important.
"There was a man who was leading an ascetic life and not eating bread. He went to visit an old man. It happened that pilgrims also dropped by, and the old man fixed a modest meal for them. When they sat together to eat, the brother who was fasting picked up a single pea and chewed it. When they arose from the table, the old man took the brother aside and said: Brother, when you go to visit somewhere, do not display your way of life, but if you want to keep it, stay in your cell and never come out. He accepted what the old man said, and after that behaved like the others whenever he met with them."-Desert Wisdom
