Not speaking for Mike, but I'm pretty sure he considered it, or he wouldn't have asked. Probably any of us that have ever been in an argument have experienced exactly what you describe, Thesis, and perhaps done it ourselves. There comes a place where it is appropriate for Paul to denounce Elymas Bar-Jesus, and perhaps you have understandably come to such a place with Essay in another venue, but most of us have some tendency to arrive at the place of denuciation rather more abruptly than we should. You are right that we should (all) be wary of subtlety and deceptive tactics. However, some caution in attacking motives, as Mike has expressed, is both admirable and wise. It is all too easy for any argument (a discussion in which disagreement is expressed, sometimes a debate, sometimes a quarrel) to descend into invective, ad hominem attack, anger and hostility that are contrary to good reasoning (and good behavior) and not necessarily helpful for clarifying the truth (more likely just the opposite). From a Christian perspective I think, though I don't necessarily always demonstrate it, that it is more important to be right than to win an argument.

Speaking the truth plainly is important. It is important that we be truthful, and that when we speak the truth it makes sense and is understandable. It is important to present truth so that people are not deceived and misled. That is not independant of the need to grow so as to speak the truth in love, with concern for how the message is perceived. Truth should serve for the betterment of those who hear, and not be angry, shrill or vindictive. I don't mention these things because I have mastered them, but because they are sound Biblical principles, and of obvious value in human relationships within the church, the family, and wherever we interact with people.

2 Cor 4:2 Rather, we have renounced secret and shameful ways; we do not use deception, nor do we distort the word of God. On the contrary, by setting forth the truth plainly we commend ourselves to every man's conscience in the sight of God.

Eph 4:14-15 Then we will no longer be infants, tossed back and forth by the waves, and blown here and there by every wind of teaching and by the cunning and craftiness of men in their deceitful scheming. Instead, speaking the truth in love, we will in all things grow up into him who is the Head, that is, Christ.

1 Cor 13:4-7 Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.

Eph 4:29 Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen.
