Oh I have on occasion.
But usually I avoid interacting with the collection of rabid anti-Catholics, rabid anti-Protestants, rabid Calvinists, rabid anti-Calvinists, rabid dispensationalists, millenialists, amillenialists, premillenialists, postmillenialists, premidpost-tribulationists, rabid KingJimmy-is-the-only-inspired-Word-because-Moses, theprophets, the Psalmist, Jesus, and all the disciples spoke Elizabethian English-ists.. (not an inclusive list - I’m sure I left some -ist out ;-) because for the most part none of them are interested in a discussion of the differences. Instead they want to staple their own label on everyone else’s forehead. With a sledge. Continuously.
Entering such a fray tends to emulate the ‘Never try to teach a pig to sing’ scenario.
You know - it is a waste of your time and it annoys the pig.
Well; there’s the Trump-Rubio-Cruz troika cage match that you could try to referee.
