I agree with you,but we must be careful of avoiding the sin of scandal as well.
There does come a point when when the same people over and over reject Eucharistic teaching and on many occasions they go way "over the top"- so to speak.
We have to keep in mind that many people view these threads and some can be mislead if we don,t completely rebuke heretical teaching.

I agree that there is a responsibility for us here, but we must be careful not to be overwhelmed. Emotion can get in the way of effective teaching.
