I think that's a bit harsh tbh. Don't get me wrong I am not sure about the wisdom of it going ahead but it sounds like you have no idea of the dedication and mental and physical effort to peak at just the right time in your career to have a stab at an Olympic medal. Just because it's a minority sport does not make it any less for those concerned and you can't just shove it 4 years down the queue as that may have been their only chance. Besides the athletes become their own bubble and are regularly tested, it's the public that is the issue.
I didn't see anyone moaning about the irresponsible football matches going ahead with fans partying outside stadiums and travelling to Europe, or is football okay?
