Does this count as telling a lie?

Ehhh, I don't think you are approaching this correctly. You should be telling your friends you don't do those sorts of things and they should respect diversity and your choice to choose for yourself than to follow what everyone else is doing because the media tells them to behave this way. If they laugh at you or make fun of you, then you know they are not people you need to have as friends because they lack maturity and are intolerant to allow you freedom of belief. You are better off with God as your only friend and to be against the entire world than you are to sacrifice your morals for companionship. God tests his followers. The true followers endure and make it through the tests.
