If you are anti-Marxist, and not anti-Semite why do you feel justified to point out the ethnicity then? You never hear people saying "I'm anti-Stalinist-Georgian", "I'm anti-Chinese-Maoist", yet it's somehow benign with Jews?
If you find the ideology abhorrent, why you focus on a particular ethnicity? It is almost as if you believe there is something special about Jews and Marxism than, say Russians and Marxism?
