Is attacking Grewnwald's character relevant here?
Anyways, if it is, Greenwald has been one of the most outspoken critics of many aspects of the Russiagate accusations against Trump(1); and in consideration of your aforementioned "liberal agenda" of his, it hardly makes any sense at all to label him on this hand a Trump defender--as he has been accused of--and on the other a 'liberal commie.'
