I think you may be right on the money, JA. For one reason or another, these souls were probably deprived of any love, and hated themselves all their lives. They found a sanctuary where they are loved, even exalted, without having to learn how to love back, so they turned their unrighteousness into faux righteousness, and boast about it.
Others seem to be Catholic apostates with an ax to grind, who left the Church because they couldn't stand someone telling them to love rather than hate. So they found refuge in those pulpits where God not only loves but also hates, so that they may also be justified din hating, as they Opel admit. No matter how you turn it around, it's pride. The NT tells us pride brought down even angels.

You really nailed it It is very sad. They do not share anything positive. Asked how they worship God they rail and bait and screech. What odd behavior. Your analysis seems spot on.
