Philosophy as a discipline is pedantry. But in this case actual pedantry is using a bunch if buzzwords you learned in your Phil101 that you don't exactly understand, inventing private definitions to argue with, and then cutting out your interlocuters.
Also the comment you replied to initially was an offshoot from a previous conversation.
When I used the word โatheistโ, I didnโt use it from as just someone who doesnโt believe, itโs also someone who claims to know and disproves the existence of God.
I understand in pure philosophy, itโs not necessarily the right usage, but itโs Twitter and I think you were a bit pedantic.
