After reading through the link you sent, and the replies gathered by the author, one can sense the agenda.

Clearly, the request for replies from Veterans, was simply a means to gather fodder from 'heroes' that could be carefully presented to show how reasonable their 'traditional' views on anti-immigration, a woman's role in the home and workforce, and the general regression of society, in the best light possible.

I wouldn't discount it as a source, but should be noted in its extreme bias, and even if many of the views presented were 'prevailing' at the time, it doesn't make them correct.
