This is a bit of an unrealistic position, especially if trying to generalise past the boundaries of your friend group. Your friends trust you, so by all means, talk to them and try to educate them. But trying to change a complete stranger's mind is almost impossible.
And many of the positions the left refuses to "debate" are that certain groups of people should not be able to exist within society. Like, the left isn't refusing to debate tax policy, it's always about bigotry.
And let's just be perfectly blunt. The vast majority of conservatives screaming "groomer" at visibly LGBT+ people aren't going to have their minds changed. You can't educate someone who does not want to be educated. And demanding minorities stand in the firing-line and fruitlessly try to educate the people who hate them, sometimes to the point of hate-crimes, forever... You have to question the priorities of such a demand.
Sometimes caring for minorities means giving up on convincing hateful people.
