I agree with your admonition that not all on the left can be painted with such a brush. But I disagree that the progressive left sentiment proceeds from a stance of being well intentioned. I too have changed over the decades. I used to be more right of center in years past, but now have moved to the left on key issues: anti-crony, anti-oligarch, ignostic atheist, pro-choice, pro-legalization of marijuana, climate change active, anti-oligarch-wars, anti-pharma lobby, pro-developing nations, pro-oppressed, anti-oppressive-religious, pro-universal healthcare, pro-disabled, pro-Palestinian and pro-Israel, feminist, pro-LGBQT rights... etc.
Life experience helped change much of that. But not everything and everyone on the left is sincere in this above set. While I arrived at many of these positions through testing the waters and a long period of circumspection, I cannot wear them as a cloak of virtue. They are reasoned commitments to serve, and have nothing to do with my identity. (Love by the way, is 'a reasoned commitment to serve')
In contrast, I sense that many of my compatriots arrived at these beliefs because they are angry at someone or learned to hate someone in their past. Most often it is religious white conservative military-structured capitalist western corporate males. I did not adopt my position by learning to hate someone who resembles people in or from my past. I also hold many positions which are right of center: fiscal conservancy, money supply, ant-Fed, transfer payments reform, limits on abuse of welfare, pro-military strength, pro-capitalism, anti-socialist, pro-company strength, pro-second amendment, anti-cartel, anti-monopoly/monopsony, pro-farmer, pro-free trade - and having come from the southern US Christian tradition, I do not hate them for who they are and what they believe.
I have had to learn to not wear the costume. There are key telltales which differentiate a person who holds their positions because of hate - and those 'who have overcome' as the Bible puts it. I can spot the difference very quickly, most of the time. But not always.
Yes, you do not appear to wear this costume.
