Some quoted studies showing liberals were more likely to commit crimes.
They didn't elaborate on the type of crime; e.g. Illegal protest vs Church bombing.

I've told people I'm a little schizo in the organizations I belong to, The Sierra Club, Jeep Clubs and an "evangelical"* Church.
  I have no problem telling the Sierra Club people I have a Jeep or belong to an conservative church. They may give me a bad time, but I don't feel threatened. I was elected to the executive committee of the NJ chapter of the Sierra Club along with 2 other republicans even though they knew we didn't always vote for their endorsed candidates. i.e. They can work with conservatives.
It's easier to be a moderate republican in New Jersey with republicans such as congresswoman Millicent Fenwick and governors Tom Kean, Christy Todd Whittman and others who were fiscal conservatives and social liberals.

The jeep people and the conservatives (most of my friends at church) really don't like environmentalists and will treat you as a persona non grata.

One member sited their support of gun legislation in a list of 5 reasons to leave PCUSA. PCUSA also supports energy conservation. "Churches should stay out of politics", some friends say.

The Southern Poverty Law Center’s Intelligence Project says that “if you go back to the 1960s, you see all kinds of left-wing terrorism, but since then it’s been exceedingly rare.” She notes that eco- and animal-rights extremists caused extensive property damage in the 1990s, but didn’t target people.

While the extreme right has held a near-monopoly on political violence since the 1980s, conservatives and Republicans are no more likely to say that using force to achieve one’s political goals is justified than are liberals and Democrats.

Trump supporters have bombarded journalists who criticized him with vicious tweets. see 2016 election hype.
