No, I'm not saying that. I am saying that if you post an article and agree with a Communist quoted in the article, don't be surprised if people start to associate you with Communists.
# 1. Guilt By Association: This is used to damage someone's reputation by associating them with an unattractive person or organization. It doesn't matter if there is an actual association or not.
If a Communist organization is unattractive, you shouldn't post articles quoting their agreement with you. It might damage your reputation.
