NotacluewhatthisisI have no idea what you mean but I do know my beliefs are radfem tenets that predate 'social media culture' whatever that is. Maybe you don't know what I'm talking about - ? Which is fine, but it doesn't invalidate my beliefs.*
I do know what you are talking about. But half your problem seems to be drinking culture and people leaning over with their boobs out, with a huge cocktail. The photo aspect is the social media culture.
I am 36. There were huge cocktails around when I was in my teens. We all took photos
But Not with a drink called porn star martini. You seem to have link the above activity with this drink. When in fact psm has only become very popular in the last few years.
I find it distasteful that you sit in judgement of women who want to take selfies with their cleavage out. No one is telling you too, so what do you find so distasteful about it? Let them do what they want.
You finding their activity distasteful has no impact on wether M&S should sell a drink that will make them money.
