Years ago I was reading something from them (this was before youtube--or, at least, before they were posting on youtube) and they quoted Saint Thomas Aquinas to "prove" someone's heresy. It was so long ago, I don't remember the subject or the subject of their wrath. Since I have a copy of the Summa, I looked it up--at least they provided the citation. I don't think they expected people to look up the citation to see the context and full explanation from St. Thomas. It turned out that they were quoting the Objection, that is, part of the explanation that St. Thomas then answered to prove it wrong. I stopped paying much attention to them after that.
