What right wing commentators?
When not here I spent some time on the political betting blog, which although not specifically a right wing blog has recently been predominantly so. Go check it out and see the level of anti left wing (and specifically anti Corbyn inner circle) posting linking him to Manchester.
Then go check out Guido - probably the most high profile right wing blogger around at the moment.
The Mail & Sun are trash rags, don't tell me some on the left don't do the same thing.
But you (in your usual someone told me way) were implying that it was the left predominantly blaming the right on this - I'm not saying that doesn't happen but I see no evidence that it is tipped that way, quite the reverse I'm seeing far more right wing comment linking Corbyn to Manchester (typically about comments made decades ago about the IRA) compared to left wing comments that might just be asking whether Home Secretary Amber Rudd and her predecessor (one T May) might need to answer some questions about failure of the security services to keep teenage girls safe when the bomber (at the least) was on their radar.
