It's only embarrasing to you and other critics though, it isn't embarrassing him, and he does persist in winning through despite all the criticisms.
I think far too many have allowed themselves to be poisoned against him by the usual persistent Tory false propaganda that he's supposedly a Communist, Marxist, Trotskyite or any other left wing insult they can devise. He's just a Socialist, who in his younger years leaned too far left as young socialists tend to do but modify with age.
I prefer to think for myself rather than let others do it for me. I'd rather Corbyn's honesty than Johnson's swaggering and empty bluff.
As for his views on the EU, he's personally opposed to membership and has always been clear on that, hence him supporting the Leave vote outcome. But he's a politician who has a duty to do what's best for his party, and currently he sees that supporting Remain could win a next GE, given how sick of Brexit the majority of the country are and the prospect of a troublesome departure from the EU.
