Hearach - I don't think you understand that tweet (or perhaps you do but are being disingenuous). It's not saying what you think it's saying at all. She isn't saying being a lesbian is 'degrading' she is saying that she thought allowing same sex marriage would 'degrade' (by which she means blur/ confuse/ change for the worse) the status of what a woman was and their treatment in society.
And you cannot argue that she has not been proven right. Even the UN now refuses to define a woman.
I don't agree that it is same sex marriage itself that has caused it (But then I don't know that she thought precisely that either), but the fact is Stonewall have pivoted to their anti-sex based rights, pro-gender, TRA stance since marriage equality was achieved, their initial aims seeming complete, and so they found a new cause to champion in order to keep the money coming in. Gay marriage has - inadvertantly - been the catalyst for Stonewall campaigning to remove women's rights and redefine homosexuality against the will of actual homosexuals.
This is not gay marriage's fault, nor does it make gay marriage a bad thing or even the voting for it a bad thing. It is entirely Stonewall's fault for choosing to champion a further, nebulous cause - not in line with their initial aims - just to stay on the gravy train. It is an act of corporate greed.
However, it is no bad thing for our lawmakers to stop and think of the full ramifications of any piece of legislation - no matter how honourable and just its intentions - before it is passed into law. Nor is it a bad thing for them to vote against that legislation if they think it is badly worded and that the ramifications will be negative and far reaching.
The baroness has said she thought the status of wome would be degraded following marriage equality being granted - as it was worded in the law she was voting on - and it has been.
Stop pretending that you think that means she has said that lesbians getting married is degrading.
