Greenwald is claiming that people are becoming less opposed to GCHQ’s spying due to their support for social issues like LGBT rights. I am asking whether there is any evidence to support that.
Not sure about GCHQ, but in the US there is a stark left/right divide in support for intelligence agencies. Notably, if you could find similar polls from 2003, the polarization would be almost completely inverted.

And how are you going to go about proving causation between pinkwashing and support for intelligence agencies? Do you think maybe the Trump/Qanon rhetoric around the FBI/CIA/Deepstate might have had something to do with republicans opinion shift? (your own link alludes to that)
