I will say it again, Starmer fan grans really need to grow thicker skins.
I have always voted Conservative (wouldn’t if Liz Truss was in charge) Tory voters and my party have been vilified since GNs inception.
I am not a blind follower criticised when I thought they were wrong, and sucked up all the jibes some were at times very personal (to MPs, and GN members who owned up to being a blue), it’s par for the course.
Your man wanted and got the top job and he and you will just have to accept that everything he does and says will be under micro scrutiny, and rightly so.
If you are finding it uncomfortable, well gird your loins only another four years and nine months until the next election…
