If a person is anxious about being reprimanded for using an offensive stereotype, they do not have the expertise to employ "culturally appropriate" materials and ought to do more research/inquiry or delegate the responsibility of the outreach to somebody else.
As I just mentioned in another post: You don't need pink office chairs to make an environment welcoming for women. You just need not to have catcalls, rapists, abusers, sexist jokes, etc.
[Edit] And for a bonus round: don't focus on culture. If you're interviewing someone for a SWE job, don't ask if they played videogames when they were kids. There is a good chance that they were too poor to afford them, or they never got it as a gift because they were females and people didn't think females would play videogames.
