Of course you think it's harmless, what else could you say. You HO:HOS think perversion and sexual fetishes are ok. It's not, it's wrong, not to mention, confusing for children.
Prove your case.
How is being gay, in and of itself, harmful? How is it a Fetish? How is it wrong, when it's not harming a soul? How is it confusing to kids?
Why would the average kid even notice or care? Young kids don't worry about such things.
Unless someone has already taught them to fear and hate.
