Borderlines are attention whores. Like toddlers who throw tantrums, misbehave and act-out to make you angry, ANY attention feels better to 'em than none at all. It's precisely the same with the Alphabet Soup gangs (woke, lgbtq..., antifa, blm).
They CRAVE our attention, and go to extremes to capture it. When you repost their nonsense, you're giving em what they desperately want. The ONLY way to stop em, is to IGNORE, IGNORE, IGNORE. Don't feed their need, and they become irrelevant.
