Do you defend your religion/nationality/race/political ideology if someone speaks against it?

Not if I believe they're right. I might softly try to defend it by mentioning (the positives) while still making it very clear that I'm aware of (the negatives), but if they're right, they're right.

Yeah. I just hurl back personal attacks back at them. And when I mean personal I mean no holds barred. Everyone and thing is fair game.

I can explain nicely why they're wrong but tend to leave the matter if it has not changed their mind.

don't have to because the person speaking against it is looking like an uneducated sap.

Not if I believe what they said is correct

Depends on what we are discussing

Not me.

I will always defend my religion.
