Programmer, sysadmin, webmaster?
What is your background?
Well, then you should know better than good layout = security...
People come on, he's not saying pretty layout = security, he is just saying he trusts more a site with a professional layout because who spends time, money and efforts for security, probably he would be dumb if doesn't pay a bit more to hire someone for a nice looking site. On the other hand if your site looks bad, you could be a random guy who built up a site to gain some easy profit.
You can agree or not (I personally don't, for the most part), but he is not comparing security to fancy look, stop repeating it
