It's really not, and I thought we'd done all of this to death on another thread.
Lots of rugby fans (and as one myself I know a fair few of them), also enjoy football. A lot of Cov RFC fans also follow CCFC.
At the same time, like a lot of other football fans (also including me) they also get frustrated at the time wasting, diving, endless dissent etc. etc. that goes on around the game. You don't need to be a rugby fan to comment on it.
Whether one game is "better" than the other is strictly a matter of opinion.
Yes there's bigger participation and more money in football, but that's like saying that Kylie is "better" than Radiohead because she sold more records.
As for the "it's only a game for fat boys who couldn't play football", I'm not sure that makes sense either. There are a fair number of rugby players who made it to academy or youth team level at some pretty decent football clubs. That's way beyond most of us here, I suspect, and I know there are a few decent footballers hereabouts.
The brutal truth as I saw it at a sports-mad, all boys school, was that the lads that were really good at one sport, tended to be good at almost all of them, and for the rest of us it was just a matter of finding something that you enjoyed. I've never seen one as being "better" than another, except for cross-country which was obviously only enjoyed by masochistic lunatics.
More rugby stars than you think almost had a career in football, including the current England Captain Owen Farrell. Check out who else makes our XI.
