Where does it say that some were "compelled", but did NOT put on a wedding garment?
The one who came without the garment WASN'T one of the ones "compelled".
You simply make up garbage as you go along.
Matt 22:8“Then he said to his servants, ‘The wedding banquet is ready, but those I invited did not deserve to come.
9So go to the street corners and invite to the banquet anyone you find.’ 10So the servants went out into the streets and gathered all the people they could find, the bad as well as the good, and the wedding hall was filled with guests.
11“But when the king came in to see the guests, he noticed a man there who was not wearing wedding clothes. 12He asked, ‘How did you get in here without wedding clothes, friend?’ The man was speechless.
13“Then the king told the attendants, ‘Tie him hand and foot, and throw him outside, into the darkness, where there will be weeping and gnashing of teeth.’
14“For many are invited, but few are chosen.”
The clear implication is that the man without the wedding clothes was a part of " all the people they (the servants) could find". There is certainly no textual reason to deduce that he wasn't invited, for how did he know about the wedding unless the servants had told him about it?
