From a thread earlier today- In a nutshell, it is because Sola pretends to be a Christian but is in reality anti-Vatican, just as many of the early generation of 'reformers' were. To their great and tragic loss, these reformers threw out the baby out with the bathwater, literally. Now, Sola follows their lead.
I agree with you, but I think it better to make the counter-argument against Sola's argument instead of Sola personally. This is probably what you mean, but the language can be easily construed as a personal attack. God bless and keep you, and sweet dreams brother! ~hugs~ Please keep me in your prayers.
