I also will not follow anyone that silences your opinion merely because they disagree. This isn't the purpose of down voting, but it's obvious to me that the supporters of anonymous feel this way.
It's fine being critical of Anonymous. Just accusing them of being "terrorists" and "having no balls" is neither constructive criticism nor an opinion worth discussing.
It's called an opinion. Garbage is spewed about the US government weekly on HN and nobody calles it "ad hominem" (which you also can't just throw around).
I provided proof. Here is another example:

They sound like terrorists, act like terrorists, so I'm going to call them what they are. I don't care if you disagree.
Christ, I'm so glad nobody here on HN is running a country.
