Considering that the more vocal people at these meetings also tend to be the people you find on sites like this babbling threats/fantasies about clashing with the government, summarizing them as potential terrorists is actually quite apt.

The fact of the matter is, if the government does make a bold move towards gun control, to about half of the country, people like this...and people like you...who claim willingness to fight against the government...will be viewed (accurately) as terrorists.
