OK. I don't want to nitpick but your response only means you voted in 1980 and/or 1984. It doesn't indicate who you voted for.
You wrote: I voted for the most conservative candidate that I could find, back then.
Why don't you do the same now?
You wrote: Who, exactly, that was, isn't your damn business.
Hmm? You only wrote that you voted back in 1980 and/or 1984. Does this mean you may have voted for a 3rd party candidate in 1980 and 1984? I'm sorry but unless you can clearly indicate whether you voted for Reagan or not, we are at something of an impasse.
If you just reply with "Yes" or "No", I will take "Yes" as meaning you voted for Reagan in 1980 and/or 1984.
Similarly, I will take a "No" response as meaning you voted 3rd party in 1980 and/or 1984.
There's a reason for a secret ballot, you are demonstrating the need.
Impasse... That's french for 'we're at a dead end'.
Still not voting for your boy.
