No you are missing the point entirely, when we believe our church fathers to be in error we must politely correct them.
Vatican 2 infallibly teaches that if one where to disagree with church teaching on the basis of his or her conscience than they do not have to believe it in there heart.
You seem to mistake infallibility for impeccability.
The church does not make mistakes no, but the people in the church do.
And than we must politely correct them so it can be changed.
I am not denying teaching, nor am i accusing the clergy of malicious intent.
I am only saying that i believe that they have made a honest mistake.
Like when they said that the sun revolved around the earth.
Disagreeing is not denying.

Let me give you an example:
I do not agree with some things in the novus ordo, but that does not mean i dislike Paul VI, in fact i think he was a great kindhearted man.
I am not maliciously denying the article i am only saying that where it up to me i would have done things differently.

And if you want to avoid socializing with sinners than i suggest you go live on the moon.
No disrespect intended i am merely reminding you that as catholics we can not judge each other for our sins like fundamentalist Pentecostals do.
Christ will judge the living and the dead (solely Christ) and no mortal should ever even consider doing so for that would like saying that thou art Christ.

I am not saying you are, but i would at least be very carefully in accusing other people of sin, unless you believe yourself to be free from sin.
Matthew 7
1 “Do not judge, or you too will be judged. 2 For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
3 “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? 4 How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own eye? 5 You hypocrite, first take the plank out of your own eye, and then you will see clearly to remove the speck from your brother’s eye.
