I'm just a man. I can make mistakes, and I have before, however, I firmly believe that every position needs to be taken to it's logical conclusion, in order to see whether it can make sense or not. Here is a simple rationale behind some of my more 'controversial' positions, and why I believe they are correct:
Believing that a person can be subject to a heretical antipope and still be Catholic or not schismatic is the same as saying that a person can join a non Catholic sect and still be Catholic or non schismatic. The leader who claims to be pope while a heretic, is in actuality the head of a non-Catholic sect, just as Martin Luther was the head of a non-Catholic sect. For that matter, being subject to any heretical religious leader (priest, bishop, etc) is being in schism from the true Church.
Believing in a place where unbaptized infants do not suffer fire, or that a person can be saved while invincibly ignorant of the true Faith or saved by baptism of desire or baptism of blood, or that canonizations are infallible means that no dogmatic pronouncement can ever be taken literally, since many dogmatic decrees, according to their literal readings eliminate all of the aforesaid beliefs as heresies contrary to divine public revelation. If these statements of the Extraordinary Magisterium are infallible, then a literal reading of them is exactly what is called for, otherwise they have to be viewed as either flawed or insufficient - but that is heresy.
Believing that children raised in schismatic sects who attain the use of reason (and are thus bound by the divine law) are still Catholic (if they were validly baptized) even if they do not believe in heresy, is to deny the positive obligation that each person has of rejecting false religions and professing the true one. Or it denies the guilt involved with the transgression (by omission) of the First Commandment. It is also an assertion that "men may, in the observance of any religion, attain eternal life," which was condemned.
If there is a flaw in any of my logic, I want to know.
