Not necessarily . . . though I think it depends on definitions.
Bigot to me is probably more narrowly defined than your definition. I would say a bigot is one who is immovably, unalterably, narrowly, rigidly, radically & irrationally partial to a set perspective, set of beliefs and practices with fierce, absolute intolerance for those not sharing the same beliefs and practices--regardless of facts, evidence, reality etc.
I don't see Proddys like that hereon. I do see some RC's like that.
However, I wouldn't hazard a remotely definitive, accurate guess as to any of their eternal Salvation statuses. I could easily be surprised. Out of the abundance of the heart the fingers fly. However, many things are not as they appear.
I can assert that some of their assertions are off the wall, or idolatrous, or blasphemous or heretical or irrational or whatever such. When such relentless and habitual pontifications cross over from merely human into deliberately outrageously sinful and rebellious or even demonized--only God knows.
My task is more to offer a type of a mirror rather than definitive judgment.
2) Is tolerance a Christian value or attribute? I think that from way up on your soap box you might find a truthful answer to either of those questions uncomfortable.
It appears that assumptions and presumptions are rampant again.
It depends again on definitions, types and degrees. Tolerance is a wonderful Christian virtue until it is grossly misapplied or operating out of a deliberate or misguided sense of what is right and proper and what is evil, demonic, destructive or what have you.
I doubt the Pharisees thought Christ was very tolerant when He was calling them sons of satan, a brood of vipers and white-washed tombs.
I, for one, believe those were the MOST LOVING things He could have said to them at the time.
I realize mileage may vary.
How can you keep a straight face when saying something as ridiculous?
