Re: Why don't the "Christians" here, use the scriptures to support their statements?
No. Because...
1. Words have ambiguity. Not everyone reads the same thing the same way, so using scripture doesn't necessarily back one's point because others can read it differently. I've cited Jesus' response to the Rich Young Ruler many times, where Jesus is asked how to gain eternal life and He gives an answer that doesn't even mention belief. Can you imagine how many different ways this has been explained away?
2. The bible contains contradictions. One of the first posts I responded to was "whether John the Baptist was Elijah", and I said that I could see either answer as correct because Matthew says he was but John says he wasn't. One of my personal frustrations was not that scripture wasn't being cited, but rather that citing scripture was the only thing people did. In this case, it wasn't enough to report what the bible said because you still had to resolve the problem of countering other arguments also made from citing scripture.
3. Not all Christian beliefs come from the bible. You won't find scripture against using swear words -- verses against "cursing" don't refer to this practice, and "curse words" are not defined within the bible (your culture defines profanity), so no one could cite those, either. You won't find scripture backing up the necessity to dress up for church, or a command to read the scriptures (for hundreds of years, only the clergy possessed bibles and it was in a dead language). So bible citations are useless in debates centered around Christian rituals found outside the bible.
Wouldn't the simple application of the Bible scripture (2Tim 2:23, 3:16) be enough to resolve the cross talking and un-Christian behavior?
