It really does matter what words mean, if you continue using those words afterwards to make a point. It is a fact that the majority of Europe has not have political parties that are affiliated with left wing ideals leading nations for quite some time. Left wing parties have a variety of shared ideals (wealth redistribution mainly), and a bunch of values that are not universal to all left wing parties (social rights, pacifism). What you are doing is calling everything governments have done recently that you don't like, 'lefty'/'leftwing'/based on 'left wing talking points'.
When it comes to the UK, one of the things we are sure of is that the right-wing, conservative, government party, has deeply cut state services, including police. The recent terrorist attacks were all perpetrated by people who were on watch lists and were actually reported by friends and family members to the police. How does the left bear the blame for that?
