When we face intimidation, we only fight harder. The better strategy is simply to wear down victim disarmers by a constant barrage of civil dialogue and facts. On the other hand, it can be useful to politically intimidate Republicans, who rely on gun owners' support to retain power. The protests against Owens were highly successful. While physical threats and purely personal attacks are always inappropriate, protests against individual politicians can garner good press and make the politician's job less rewarding.
Individuals pursue activism in their own ways.
While I've been to most TRT rallies, I've spent much more time working on my web page and with Libertarian projects. Even someone who has never attended a TRT rally might have an insightful criticism to offer. If that were true, then all the disarmament laws would be a success. People should get active, sure, but they should do so in ways that actually help society become more free, not in ways that alienate potential allies and confuse the message. The press coverage of January 8 did not present our message, because the TRT did not present its message to the press.
