I feel like it'd just give you pictures of happy couples doing SFW couple things or old dudes at pride. Even with safe search off, it's not like the phrase is explicitly pornographic. In my experience, you need to be very direct to get NSFW stuff in general from Google.
Maybe I'm just deep into the queer community, but this meme feels like it was made by a person who sees homosexuality as inherently taboo or lewd. Kinda stale tbh
