Seriously. Deacon will be 30 in a few years.... and we're still talking about his actions in terms of Glenn's parenting??
Niall Horan is the same age as Deacon. If I went to a One Direction board and criticized something Niall has posted on social media, I wonder how many fans would accuse me of maligning the parenting skills of Niall's father? Or talk about how it was such a shame that anyone would criticize the son of Bobby* Horan?
Deacon is a grown man, and he has been for some time. Judge him on his own merits, and by his own actions.
*I looked up his dad's name - thanks Wikipedia
