In your book, I doubt anything Corbyn did would get a recommend from you, however good, useful or helpful!
If you looked back at various politicians' mumblings over the years you'll see some pretty nasty offerings - from both sides.
For me, one of the most unpleasant and downright unecessary comments was made towards May, a woman I do not hold in esteem, by Leadsom... you will probably remember the observation about her not being a mother.
Even though I have little respect for May, I felt quite hurt on her behalf - a woman who had admitted in public that she would like to have had children, but couldn't.
What I'm trying to point out is that many 'pollies' say things that are out of order, they get attention, then they get forgotten... unless it's Corbyn - who is constantly invoked as the devil incarnate in some quarters.
... also, it is possible, if you allow objectivity to rule your head rather than hatred to rule your heart, you can respect and even empathise with your political opponents, when necessary.
I would have found May's face being used as target training as repugnant as using Corbyn's.
