Noticing breasts is one thing, unwarranted personal comments is another. They are disrespectful. Complimenting a smile is not. Huge difference. As for “verbal abuse,” this goes to both personal boundaries and
courtesy, rule of thumb, don’t make sexual comments to any woman in a public place, or in private without her permission. Verbal belittling, swearing, etc is unacceptable anywhere. If you are unsure of a woman’s boundaries, ask, she will respect you for it. I recall one of our male sf posters who altered his opinion of what constitutes abuse, spoke up, and earned the respect of many members, both male and female.
