The problematic thing is the implication that holding a similar view automatically makes you a part of the same organization.

Terrorist groups are more traditionally defined as an organized groups that use terrorism as a military tactic to achieve their goals.

noblogs.org never used such tactics nor supported them.

If we call anyone a terrorist, if they have at least one view similar to those who did terrorist acts, we only need 2 quite specific terrorist acts to cover all earths population.
