When I argue, will I lose friends?

[eageryear757]

I have have the thought that when I stand up for one of my beliefs (e.g., writing articles) and posting it out there for people to see and get the word out that my friends will disagree with my articles and not be my friend anymore.

I have a few questions:

1) If they argue or send me a comment about the article disagreeing with me, what should I do? Should I argue back with reasons that are valid - I just don't want to take an argument to go down without my thoughts.

2) If they don't let me come over anymore is that wrong?

3) Is there anything as a friedly debate that would't end in any hatred of the other person = perhaps I am being overly pessimstic about standing up for my beliefs?

I never introduce my beliefs directly to anyone, I usually just post articles and twitter them and facebook them so they have the choice to read them. This should be carried in mind.

After reading all this, if you can answer at least one question I would be grateful. Once again, I am a really friendly person but scared to stand up. Should I start?
