When are the next ex raid passes appearing?

You're missing out! It is October and you get a daily raid pass and 50 extra coins for nothing...that is 20-25 Gengars you are passing up on

Why are you still here 'retired' guy ?

Niantic is waiting for you to come out of retirement. They are most concerned about you. All other profit seeking measures have been put aside and all of Niantic's employees are focusing their efforts on getting you, harrytipper2, back to the game. I think I speak for the whole community when I say that things just aren't the same without you Harry old boy! Please come back so that everyone can get their Mewtwo!

I'm thinking it has to do with the recent events in Florida, Texas and Nevada (Vegas)

You are asking when the next ex passes are coming but "no wonder spend time hoping for them". Retirement might be a great opportunity for you to brush up on grammar and logic.

Retired from pokemon go?
Pardon my french but L-O-L.
