If this comment is an indication of how you approached the conversation, maybe you failed to convince your colleague due to a lack of specific arguments and an abundance of scornful conceit.
The context is that I was shopping around for houses, doing inspections and such, and was merely curious about why homes were constructed in such a way. My home country primarily makes homes out of concrete and brick for heat insulation and it works well, compared to what I have to put up with a Texas heat wave in a wooden house currently.
I'm not entirely sure why you're assuming that I had no specific arguments though - I certainly wouldn't put a whole conversation verbatim onto an internet forum.
