No they aren't, whereas you making a comparison with Paris-Roubaix only evidences yours. I think this is another case in which the Tour has gotten too big at the expense of other races on the calendar, particularly Worlds. It started perhaps with Indurain, although became a matter of praxis under Armstrong, then Contador and Froome, whose repeated absences at Worlds diminished the race. I don't think that's disputabile compared to the Worlds up through the 80s and the spirit and prestige that surrounded the event at the time. Now one can find nothing wrong with it or think it a shame, and I've read articles in the past voicing complaints over Worlds not being what it used to be on the calendar. I don't think the criticism is baseless, let alone ignorant, but seen through lenses that have watched the sport over many decades.Your opinion is fine. You're entitled to it.
Arguments, though, are unveiling ignorance.
