The word conservative has a political ring to it and political parties can encompass a varietiy of tenets within reason.The Church is not a political party and there is no room for diversity of belief in matters of Faith and Morals.This is why from the very start Creeds began to appear. I prefer the word orthodox when speaking of religion.
Because of this I only support orthodox speakers addressing any Catholic religious gathering precisely to avoid sowing doubt and doctrinal diversity. 
I post here to counter any heterodox opinions being propagated either in the articles or the comments section. I don't expect to have any effect upon the regulars here but I am trying to "protect", your word, anyone who may think that everything  they read here is orthodox Catholicism.
I don't judge individuals. If my tone is shrill it is probably in response to shrill reply. I'm not the only one who responds negatively and only do so when I disagree with something, which I admit is quite often.
