Remember what it turned us into, what we became, unabashedly, afterwards.

Remember how it broke our collective minds and caused us to go into a violent frenzy that only made things immeasurably worse.

Remember that.

Remember to never let that happen again.

Remember that we are still in the midst of that collective frenzy, and while you personally may not be able to directly stymie the violence carried out by the powers that be...

Remember that you can hug your neighbor, not hate them, that you can see every other human being as fundamentally another human being, whom should be lent a helping hand, not a closed fist nor veiled threat.

Remember that you can do that right now; promote love, instead of hate, inspire curiosity, instead of fear, foster acceptance and community, instead of isolation and atomization.

That, that is the ultimate antidote, to why what happened that day, and afterward, happened.
