Owen Jones is also on the very left of the party, which is probably why he didn't come out and provide too much of an analysis. The reality is that the tweets she liked probably weren't that terrible, it wasn't calling for a genocide etc, but the optics were bad. Especially after the report into anti-semitism. MPs are held up to higher scrutiny than other people and she wants to run - you gotta watch what you say in a public forum when you're an MP.
