I think the end of this is a good way to see it. Sure who cares it's a way to let the UK honor historic people. But don't pretend like it's some big feat or victory for oppressed people. Pardoning and putting a him on a note doesn't undo that.
And besides, why if the case is to show respect is Winston Churchill on a note? A conservative primeminister in power when Alan Turing died. His party and their policies are in part to blame for what happened. Using Churchill as a figure and hero, while at the same time advocating for things his party was against. It makes the whole thing fall apart in my opinion.
You can either use the notes to display historical people, or to display achievments and values. I think it seems like they tried both, and it comes of as contradictory
You really truly can't compare the two in any substantial way. One of which was the murder of entire segment of the population as a method of reducing visibility and acceptance. You don't see the general public killing, maiming, or abusing cannabis users at any scale similar to that of the homophobia that permateated, and permeates the entire structure from the weakest on the social order to the most powerful.
You just can not compare the removal of reproduction, the imprisonment of a minority, and the victimizing of things people can not control to the act of voluntarily smoking or ingesting of any chemical.
This may be propoganda, but this is propoganda that is a net benefit for all involved. This gives people hope that things can be better, this gives people hope that things can change, this gives people a nod that homophobia is not the way to go, and to be more accepting. This is a representation of the highest level of government bending to the will of the people.
You just can't compare the two.
