That "or" is doing a lot of work.

Interestingly, according to various surveys antisemitism is higher on the right of the political spectrum, but criticism of Israel is higher on the left.

If you wanted to give pundits on the right the benefit of the doubt, this means people they mix with that criticize Israel are very likely to be anti-Semitic as that overrides their political bias towards not criticising Israel.

Of course, more cynically, this makes equalising anti-Semitism and criticism of Israel a good political move for the right as it effectively neutralises one of their longstanding flaws. "Both sides are the same".
