Yes, you have Calvinists murdering Catholics, Catholics murdering Calvinists, Baptists murdering and being murdered by Calvinists, Anglicans persecuting puritans, etc. etc.
All have sinned - and seriously, raising this ruckus on a post where the article in question does not say one bad thing about the Baptist church that the author originally came from - why the entire animus?
You seem to have missed "when I left Protestantism (I was Southern Baptist*) and I was looking for the True Church... It wasn’t the Baptists or the Pentecostals, and it wasn’t the Eastern Orthodox."
And thus based on his myopic blindness and erroneous reasoning of false equivalence, he not only even places Baptist etc, but even the EOs as not being the "True Church" (which unlike the Baptists or the Pentecostals, they also claim to be).
For in his own words he is a "Red Trad," one who asserts that the Catholic church has "lost all credibility in the public mind." In which "A large portion of our hierarchy has been screwing men. They’ve created a network of gay buddies, and they protect each other and promote each other. If investigators get too close to exposing their shenanigans, they could potentially get killed off by henchmen in a mafia run by sodomites." " We have a pope with close ties to the sodomite network who denounces investigators as detractors." "We can’t even go to confession with the confidence that we’ll be properly absolved. The authority of the priests has been taken hostage, and the world and most Catholics cannot understand this." "they’ve captured the dioceses by violence, and you are on the outside. They have the buildings, but you have the Apostolic Faith. They got those buildings, but they are outside the Faith." - http://forge-and-anvil.com/2019/02/24/stay-sane-during-the-sex-synod/
I am not saying his allegations are wrong, but just imagine what the reaction would be by many Catholics if one of us said those things. Still, unlike the SSPV types here, he at least affirms that pope Francis is the validly elected pope.
Yet this visible church is what Catholics want us to leave conservative evangelical fellowships and join, a perverse amalgamation of false teaching and false believers amid some that are true in both respects.
