2 adjectives to describe controvertist

But whether it be that "small things make mean men proud," and vanity catches small occasions; or that all contrariety of opinion, even in those that can defend it no longer, makes proud men angry; there is often found in commentaries a spontaneous strain of invective and contempt, more eager and venomous than is vented by the most furious controvertist in politicks against those whom he is hired to defame.

I must for ever remind these puny controvertists, that those acts are laws of permanent obligation; that two of them are now in force, and that the other expired only when it had fulfilled its end.
