I don't argue much any more, the only time i really really dig in is if i feel like someone in a more junior position (work, life, or otherwise) is being harmed by someone in a more senior position. I've fired Sr devs and managers for being assholes to new grads. I've threatened disownment to direct family members for filling my kids heads with toxic political opinions. When someone in a perceived position of authority is doing harm to someone subordinate to them then that's a battle i'll fight. Most other battles i just don't care enough about to spend the energy on .
