It is not my purpose to debate with you, only that you sincerely examine what you are saying to see if it matches what you really mean to say. Does this wish arise from God, or from some other source? You wish men you call heretics to lead not only themselves but also others astray? Do you find such a notion in Scriptures or the tradition of the church? Paul encountered a situation much like this in Corinth, when those who embraced herectical or immoral ideas spread by the false teachers influenced the church, and he reprimanded them harshly and attempted through his acts to bring them to repentence. He certainly didn't tell the leaders of that church to expel these men and to throw them into another flock!! His instruction was founded on love; to forgive the offender(s) who repented (2 Cor 2:5-11) and even for the unrepentent, the step of removing them from the church was done in love, with steadfast hope of their eventual repentance and salvation (1 Cor 5:1-4). You appear to have no love or concern for the salvation of either the wayward brothers in your own denomination or those you believe are misguided in other denominations. I will pray for you, that you would receive God's grace in abundance, and that you might give mercy as freely as He has given to you.
You can’t forgive a heretic until he has repented. If people do not wish to abide by Catholic doctrine, they should be honest and separate themselves. Staying in the Church lets them lead many, many more people astray than if they left.
Their repentance and reconciliation is always a possibility. But they have to do it, and cannot be kept within the bosom of the Church to poison others if they do not do so. And the bishops are falling down on their duty to protect the flock if they do not declare this.
