Imagine you want to play a game of tennis, and two strangers offer that they'd like to play with you, separately.
The first comes to you as you're waiting, racket in hand, totally naked. He then holds out a cement brick and refers to it as his 'tennis ball'. He asks if you want to serve first. He then states that he will use his psychic powers to hit the 'ball' back at you if you go first.
The second similarly comes out to you as you wait. Everything seems normal other than how he's accompanied by a spectator not previously announced. You shake hands, and the spector holds out a submachine gun. You're now informed that whomever loses the game is to be immediately executed for their failure.
This is what debating politics amount to.
First, we have entirely different views of what factual reality exists in the world to the point where we might as well be literal space aliens to each other.
Second, the punishment for failing to properly achieve a political cause is literally either direct physical harm or death (not always, but often enough and especially on the biggest issues such as abortion and gun rights).
