The Church teaches homosexual acts are seriously sinful. The Bible says the same. This has always been the teaching of the Church.
If anyone says homosexual acts are not sinful, that gay marriage is a good thing, they are contradicting firmly established Church teaching and inspired Scripture. They present a danger to souls.
Therefore, the Bear will call them out.
Here is something that liberals can understand.
If the Bear made a statement, "All redheads are half-human parasites that should be shipped out of the country," a liberal would spring at the Bear with words like "bigot" and "hateful," and start wailing about judging, etc. [Note: actually, "redheads" are not a Recognized Victim Group, so they wouldn't really do that. They only get tolerance points for RVGs.]
And they would be right.
Sometimes it doesn't take much of a sample to know the whole sandwich is spoiled.
That's how the Bear knows that someone who contradicts well established Church moral teaching is in trouble with their concept of the Church. There are many other belief systems they could join other than the Church. But the Church says, (a) you don't get to make up your own moral theology; (b) you are not always safe following the world's beliefs; and (c) you must accept the Church's moral teachings.
There is nothing difficult to understand. If there were no clear moral teachings from the Church on homosexuality, the Bear couldn't care less. But it so happens that there are.
The Bear's natural inclination is to live and let live. He bears no animus against homosexuals. But his moral life does not stop at the end of his cute snuffly nose. He is docile to the Church's teaching on moral matters. That is why he shrugs and must follow the Church's lead on this.
Again, this is not difficult. It is not a close question, or something reasonable Catholics may disagree about. Once you espouse the Cause of Homosexuality, you have stepped outside the Church's charmed circle of safety. You are imperiling souls by celebrating serious sin for which they may go to Hell. And God only knows what you will do or say next.
The real question is this:
Why is liberals' need to feel socially superior by holding to so-called "correct" views taught by the Prince of this world greater than their compassion for brothers and sisters who are trapped in sin and at risk of Hell?
But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised. But he who is spiritual appraises all things, yet he himself is appraised by no one. For who has known the mind of the Lord, that he will instruct Him? But we have the mind of Christ.
