No disrespect to Mumsnet posters but GNs are a bit older and sometimes longer and wiser in the tooth.
The OP has posted beforehand, at the beginning of Jan this year,
The post was regarding taking her 12 year old GS and his 18 year old sister to a restaurant, the DGS was wearing a pair of Ugg boots which the OP had bought him for a fiver.
According to the sister the DGS had been stared at because of his Ugg boots?
The crux of the OPs question seemed to be Does wearing Cheap Uggs mark you out as being "Openly gay" at 12 years old?
Interestingly the OPs posts have both appeared during school holidays. This original post was eventually deleted by GN. Make of that what you will.
