I think there has been an invasion, but also that there are lots of members that are unwilling to see the worst in people and would rather stick their heads in the sand.
As for who to vote for, it’s always worth looking carefully at your actual candidates - in LE you might have some good independents fighting for uniquely local issues, and in both LE and GE you might find there is lots to vote for in particular candidates. Good MPs are accessible - mine can be found washing up at various local events, for instance.
Regarding the women’s rights issues, remember, we have allies that feel they cannot currently speak out - I know a number of my local labour councillors are anti self ID - you won’t find that written anywhere, but I know that they will be doing the right thing behind the scenes. I’m sure there are Green and LibDem councillors who are the same (I just don’t know them)
Re: the anti Semitic stuff - it definitely exists within labour (albeit mostly in stupid conspiracy theories about worldwide banking control etc, rather than actual hatred or Jewish people) and it definitely hasn’t been dealt with swiftly enough.
Someone I know shared a social media post about one such conspiracy. When I pm’d her to point out that it was a narrative begun by actual Nazi propaganda, she was horrified.
Such is the problem with the internet. I wish I could come up with a solution!
As for who is representing remainers - only the Lib Dems - after the coalition government I wouldn’t trust a Lib Dem to hold my beer while I nipped to the ladies, but I realise this is an important issue for many, so no judgement!
Spoiling ballot papers is good though - I’ve been to the count for both local and general elections and every applied ballot must be looked at by all the candidates and their agents before it can be declared invalid.
So if you write something relevant as to why you can’t vote for any candidates, guaranteed your mp/councillor will read it.
