A vehicular cyclist is a cyclist riding as if they were a car, so in the middle of the lane etc. It’s the adviced way of cycling when there is no proper infrastructure, as sticking to the side makes you less visible and more likely to be dangerously overtaken. It depends on the context of the road whether it is the best way, but I would not call them the problem, just a bad solution to a problem that should be solved by infrastructure.
Only “vehicular” cyclists are an issue, but TBH even other cyclists hate them.
