There are dozens of articles and several studies that confirm strong ageism in men preferences for relations. Few mention that single career women over 35 are the most unhappy people and a quarter are on antidepressants. From here to taking action against the relations of their age group men with younger women is a tiny logical step.

No idea what are the "certain circles around the web", but the overused word "toxic" gives me an idea: it it men in general? I saw the Gillette commercial.
