There are some good points here, but I think the take away is incorrect. Don't stop arguing with people... change your strategy away from winning. Much of the advice given still holds.

A well-conducted argument serves important purposes.

- It flushes out good counter arguments to consider, or at least valuable historical context to help build empathy.

- You can set a better example for others to follow, as we all have this nearly irresistible urge.

- You're quite unlikely to change the mind of the debaters (yours included, hat tip to Dumblydorr's comment!) BUT you might sway someone on the fence who is a witness.

- Finally, I'm a firm believer in the idea that it's nearly impossible to change our mind in the moment, and only by taking a public (even if with just one other person) stance and holding it seriously (even if... ESPECIALLY if it's a ridiculous stance) can we move past it. If the idea perpetuates itself forward only in your head, you'll never dislodge it.

Don't stop arguing, but argue with humility, style and respect.
