Perhaps we should thank the LDs. Up to now the debate over self-ID had been, well, #nodebate. Many people will have been unaware or presumed that the fuss was about something arcane and nutty and nothing to do with them.
But it is. It is about someone like Nick Robinson being able to walk into the women's changing room in M&S when your gran is being fitted for a new bra, simply because he feels like it. And a political party is on the radio bragging that they see this is a political priority, and a reason why people should vote for them.
Blokes on twitter are not buying this. Nor will the man on the Clapham omnibus. Lets hope the LDs carry on, and that the election proves that announcing you will impose self ID is political kryptonite.
The Tories have worked this out. I think John McDonnald also realises and will do his best to keep the issue low key during the campaign, as will SNP where some brave women have already spoken out.
