Is conor mcgregor a bigger icon than floyd mayweather?

In the US maybe, but internationally Mayweather is likely known only by other fighters.

not by a long shot.......................

No he is not, he's not half as good!

No. Apart from anything else boxing is more generally popular than MMA so I don't think so.

Nope, he sure isn't.

No, Conor McGregor is one of the better known Mixed Martial Arts Fighters of this era and he "might" make my Top 30 of Mixed Martial Arts Fighters of All Time. Whatever you think of Floyd Money Mayweather, when you look at Pay Per View Buys, he is the only one ahead of both Mike Tyson and Oscar De La Hoya. Mayweather is Money. 

No. No  matter how hard they try and sell it.

If you are comparing sport to sport, Yes he is, McGregor is the first name that comes to mind when you hear MMA, he is also the richest MMA fighter by a lot. Whether you like him or not, whether you think he is a good fighter or not, it doesn't matter, he is the top dog in that sport and he can't be replaced, Floyd was replaced the second he left, he was replaced before he even left, MMA cannot replace McGregor he is their biggest money racker, so it that sense yeah he is a bigger icon.

Yes, that's why he got more money for the fight.... Oh wait

i would hope not
