Plowing cars into groups of people is mostly done by people following an ideology which is not generally considered to be "left" or "right" as those labels are not used to describe religiously-inspired movements. In the 2017 EU Terrorism Report [1] - The EU being where I'm based and as such where I have most experience in these matters - done by Europol it is shown that the "left" is a much bigger threat than the "right", with 27 terror attacks executed by "left-wing" terrorists versus 1 attack by "right-wing" terrorists. As an aside, "nationalist" groups are responsible for 99 attacks. Islamic terrorists are responsible for the majority of deadly attacks (135 out of 142 were killed by jihadis). As to what concerns the amount of "trolling" (in which I include breaking in to sites and downloading their data for later perusal, defacing sites, DDoS-attacking sites and similar actions) done on the 'net I'd say that, at least in Europe, the "left" is far more active than the "right", partly due to the fact that the "left" is better organised. One of the reasons for their better organisation is that "left-wing" organisations are given far more leeway than "right-wing" organisations, something which is related to the difference in reactions to "left-wing" icons (both the older ones - Lenin, Stalin, Mao et al - as well as the newer versions - Castro, Chavez, etc) versus "right-wing" icons (mostly Hitler and those around him). Public support for the latter is a punishable offence in some countries and frowned upon in most. Public support for the former is no problem whatsoever and done quite openly. I've never seen people carrying banners with the portrait of Hitler, I've seen plenty carrying portraits of Marx/Lenin/Stalin and Mao. I've seen banners telling us to follow the good example set by Chavez in Venezuela. I've seen a book fair which has "Lenin's corner" as a regular feature. Not some niche left-wing book fair either, the biggest one in the country and the focal point for the cultural intelligentsia. Could you imagine a book fair having "Hitler's corner"?
