I think this is the right attitude and shows authenticity. If I am angry that someone blocked me yet happily engaged with them in the past, it devalues the past engagement and makes me question if it was authentic. We should value the good times we had sharing comments with another writer rather than react if they block. Nobody knows how someone's real life is and judging someone based purely online isn't the best way to judge when we don't know the person in real life. We can't force others to do what we want or engage.
