cian's dolls

Got a youtube comment today, which was a pretty nice comment complimenting the doll in the video and which I wouldn't hesitate to reply to, if not for the fact that they mentioned they were waiting for a factory blythe to customise. And man, I do want to reply to the rest of the comment, but I'm not too sure what I am supposed to say about the factory blythe when I'm not supportive of any un-legit dolls. I could just not mention the factory blythe in my comment, but I'm not sure if avoiding it in that way is inappropriate and also indirectly allowing people to assume I am alright with factory dolls.

As I said in an earlier post, I am against factory blythes and recast for myself, and I do not wish to see my doll friends have them, but I do know that that is not within my control, so I try to avoid people who do have such dolls. But when it is a comment on my youtube video, I feel like I should (and I do generally want to) reply to comments, but the factory blythe bit throws me off. I could of course just not reply to the comment but I'm not sure that's the best course of action... Sigh. I am not going to say mean things about factory blythes to the person, of course, but what should I say while making it clear what my position is? (I know some people probably wouldn't care, but I find it quite important to make clear my stance?) :/
