I can't think of a more "parent friendly" comic company than Dell, extending into Gold Key. They excelled at providing wholesome material. But calling other publishers' product filth isn't/wasn't necessary. What the general public never seems/seemed to get is that comic book product has such a vast potential for communicating to audiences of countless age and lifestyle leanings.
Even today, comics specialty stores feature kid products in dangerously close proximity to some very adult material. In 2025 USA, I would caution greater vigilance in product display. Remember that in the Friendly Frank's store case which rocked the industry, the offending materials were behind the counter.
