In my experience, people who go around quoting the bible everywhere, invariably end up playing bible quote poker, where each has to counter a quote with another.
It's pointless and invariably end up with one making pseudo-intellectual insults at the other.
If you follow Jesus, it's all pretty simple really. Don't judge. It's part of the 3rd commandment. It's a corner stone of Christianity and frankly, if you accept the judgement of others, even just to get peace, you have essentially submitted to non-Christianity.
So, if you think about it, not worrying about the judgement of others is the correct course of action.
Those that claim to have the authority to judge you should be avoided at all costs.
