Lie. You were talking about the tax cut and it's effect on the economy.
No, we weren't.
Try to follow the thread.
We were talking about revenue, and your "very fine person" friend insisted that the tax cut, that was signed in late December 2017 and took effect January 1st 2018, somehow, someway increased revenue for 2017.
Then he realized halfway through that the tax cut didn't take effect until 2018, and 2018 saw less revenue than 2017.
Then he tried to say that revenue went up in 2019, which it did, but the increase in revenue between 2017 (no tax cut) and 2019 (tax cut) was less than inflation over the same period.
Then you butted into the thread and pretended our dozen-post conversation was about something else, and the reason you did it was because you are trying to derail a thread where one of your pals got his ass kicked.
