ARE CONSERVATIVES MENTALLY ILL?

Why is it that almost every time there's a mass shooting they discover that the shooter had ties to conservative groups? There always seems to be ties to alt right, neo-nazi, anti government militias, anti abortion, white supremacy and don't tread on me, tea party, trump supporting type groups. It's never someone who is associated with organizations like Greenpeace or The Sea Shepherds. It's never someone who is anti war and feels that war should always be a last resort. It's never someone who is for a woman's right to have an abortion. It's never an advocate for clean air and water. It's never an advocate for equality, education, marijuana legalization, sensible gun laws, gay and LGBT rights and accepting science over faith based beliefs. It's never a progressive liberal like me!!! No, it always seems to be someone who identifies as a conservative and who is a proponent of conservative values. So if these mass shootings are nothing more than mental illness as President Bonespur says and the gun laws as they exist today are not contributing to the problem, then the only thing I can conclude, based on the evidence that I have outlined, is that conservatism is a form of mental illness.
