Older brother is a kilt kop

[Mad Dawg]

I have no desire to “go commando”

To “go commando” is to go without underwear. Nobody is suggesting you do so. In fact, a large majority here will encourage you to wear underwear.

…it’s not a fear as such…

I’d rather have that then sexual harassment

Throughout this thread you have made it clear that you have a fear of some sort. If your concern is sexual harassment, then you have our full empathy. Again, we can help with that. I, for one, am having difficulty in understanding where you are coming from.

...the meat of the thread was how to deal with my older brother who is anti kilt and anti Scottish.

Your brother is a dick. Ignore your brother or tell him to get bent. There really isn’t much else to say on the matter, unless you wish to provide more details. Frankly, your mode of wearing a kilt is a more interesting topic.

…my mom said she would wear trousers underneath too as a kilt is relatively short…

Your mom is not wrong. It is, in fact, relative. Relative to an ankle length dress, a kilt is indeed short. Compared to a mini-skirt, a kilt is quite long. Kilts are longer than most shorts. Do you wear shorts? If you do, do you wear trousers under the shorts?
