The problem isn't older looking characters, I love the games by Talothral, some of them have some old looking characters that truly look like grandmothers, the problem here is you have characters that looks like mythical hags, my grandmothers in their 80s didn't look anywhere near as terrible as Rhona, Morag or Sandford's wife do, their is a difference between characters that look old and hags, and the Dev of this game got some pretty extreme notion of what elderly people are supposed to be looking like... or perhaps humans altogether.
Also the whole thing about 'if you aren't happy just go elsewhere' its all fine and dandy but it doesn't mean one is devoid of opinion on a subject, people like you are pretty much one of the issues with modern politics, namely you want an echo chambers that reflect merely your point of view and if people don't ascribe to your point of view they can just shut up and leave. Its not how it works and it shouldn't be how it works, if you have a diverging opinion its your right to express it, but so do I share the right, its not like my opinions were some offensive rant.
So ultimately I'd answer to you, if you don't like my comments don't read them and don't comment back on them, if that is how you think it should work, than don't be an hypocrite and ask others to abide by different rules than you do.
