I don’t think that is remotely complicated. The Pride Flag and the EU flags are flags of togetherness and unity. The Palestine flag is a flag of a victim, like the Ukraine flag. The British flag and the English flag have both been commandeered by British racist groups.
This is exactly my own point of view.
The Union Flag is particularly ridiculous because it includes the Scottish saltire which belongs to a country they barely wished to remain in the United Kingdom. The St George Cross needs to be binned sooner rather than later.
