They regarded Humans to be inferior and particularly opposed Human involvement in Vulcan culture. ()

The group were separatists, working to have  withdraw from the Federation, which they considered a "failed experiment". ()

Logic extremists bombed the Vulcan Learning Center in an attempt to kill the young Spock, as he was the child of Amanda and Sarek, which they viewed as contamination. This attempt resulted in his adopted sister, Michael Burnham being dead for three minutes before she was saved by Sarek. ()

In 2256, the logic extremists sought to sabotage an intended peace meeting between Sarek and two Klingon Great Houses. The extremist V'Latak, who had been assigned to pilot the  transporting Sarek, gave himself an injection en route that caused his body to explode. This suicidal attack disabled the ship and severely injured Sarek. ()

Admiral Patar, a high-ranking member of Section 31, was a logic extremist, and according to Katrina Cornwell, a particularly fanatical one. ()
