I was in an argument with someone bashing my favourite Catholic apologist, claiming he was 'unauthorized' and therefore preaching lies and things contrary to Catholic doctrine. His friend joined in and claimed that he was excommunicated by the Church.The person in particular who they were bashing was Michael Voris. I tried to defend him, but I ended up deliberately lying about Canon Law and what it says (Just at first, I claimed that Canon Law says you didn't have to be assigned with a certain diocese to be approved, just be supported by a Bishop. This is wrong). The guy in the argument was talking like the USCCB was the Vatican, and in anger I accused the USCCB as being a left wing liberal organisation that produces watered-down articles and documents about the faith. The argument evolved and eventually I was saying that the USCCB was not an authoritative body, making what the USCCB said about Michael Voris being irrelevant.
He claimed that I was a cafeteria Catholic for not accepting the USCCB's 'teachings'. I became really annoyed at this and argued that the USCCB does not have 'teachings' but 'opinions' on various teachings which a Catholic is allowed to accept or not. He claimed that I was accusing the USCCB of giving 'watered down teachings' when I repeatedly said to him I was referring to the documents and articles it produced, not what it 'teaches' because the USCCB does not have 'teachings' the magisterium does. I'm just mostly worried about myself lying about Canon Law!
Am I excommunicated because I lied about Canon Law to him? I was wrong on several things, could be more, but I really am sorry. I was just in a bad mood and I don't know what to do next. In summary I claimed that the USCCB does not have authority as an organisation, and he said it does. I said that the USCCB gives watered down articles, etc about Catholic teaching. He then claimed that I was saying that the teachings the USCCB give us are 'watered down'. I again affirmed that the USCCB does not give teachings and dogmas and to think so is heresy and that the USCCB gives opinions on things on which we are free to decide to accept or not accept.
Okay. A couple of points here...
The USCCB is not, by itself, the Magisterium of the Church. The Magisterium of the Church is the Pope and (all) the bishops in union with him. IF the USCCB teaches anything contrary to what the Church teaches, then there is a problem, but it's not with you. It's with them.
Heresy is defined as the post-baptismal, obstinate denial of a truth which must be believed with Divine and Catholic faith, or likewise, it is to hold an obstinate doubt about the same. This implies that you know what the Church teachings, have been baptized, and reject the teaching.
So, to answer your question... Is the USCCB teaching something that the Church teaches, and you obstinately reject it? If so, then you are technically a heretic and automatically excommunicated (latae sententiae). This would have to be a willful act, not an accident.
