Children at concerts are increasingly common - many parents are great about, others not so much. Most of the concerts I have been to are in bars, lots of alcohol, sometimes drugs. The first group of parents realize this and make sure their kids are prepared, know to stay out of the dancing ( or moshing area) and don't use their kids to get special privileges. The second group uses their kid to push up front, declare that there.shall be.NO.drinking.of.any.kind. and and gets upset when the band speaks like they do on their records. This father seems to be the second group.
Here's why I think so: He was told not to bring the kid up front, did so anyhow. Second he put her on his shoulders, blocking anyone behind him for several rows from seeing the show they paid to see. Then gave her a sign to wave, making sure may more people could not see the show they paid to see ( so his kid and the sign have more of a right to see the show than hundreds of others), then gets pissed at typical behavior for the band in question.
This is the type of parent that makes folks call for adult only venues - and if were a parent I would resent them more than those with out kids do.
Townshend should not have apologized...that is only going to make people like this more entitled. And frankly. I think the father and child should have been kicked out for interfering with so many other people's enjoyment of the show.
