um hi i’m new here but i have an opinion i guess. i think we are but when i say war i don’t mean fighting i mean political rallies differing opinions and cultures and ideas and they all clash so hard. not all wars are fought on a battlefield. most are fought in our minds and minds of others. somethings gonna have to change and i honestly think a ‘war’ is the best way to do it. fight it out. stand up for what you believe. it’ll work out. freakin united states of america we’ve got this.
