I wasn't a SAHP but I'd spend time with my kids at a park nearby and people would give me dirty looks for playing with my kids if my wife wasn't present.
The internet convinced me it was going to be a problem, but it literally never happened once.
We rotate through parks because the kids love seeing new parks. Nobody has ever given me a dirty look for bringing my kids to the park. It’s a completely normal thing for parents to do.
