I for one promote tolerance and education for Tekkit/Technic users. Probably because I started as one myself. Most people come across it as their entry-point into the modded-minecraft world and are naive to the way it operates. I thought it was all kittens and roses until I started going to Mod's homepages/forums and saw the real sentiment. I like the idea of modpacks still, and now use FTB.
My belief is that if people act like an arse to anybody who mentions the word tekkit/technic they'll get the impression that the community is unfriendly and in turn feel less sympathy for the treatment of the Mod author's rights by the tek crew.
tl;dr - make the perpetrator look like the douche, not the victim
