Please help with the meaning of following sentence:
"Some like the word naturalist, meaning a person with no supernatural views. This really appeals to me in one way, but naturalist instantly brings to mind David Attenborough in a safari hat, whispering and pointing at a rare blue-footed booby. Other people prefer secularist, though this technically has the narrower meaning of an advocate for the separation of religion from public and political life."
Thank you in advance
A blue-footed booby is a bird. The person is saying that the phrase "naturalist" makes them think of David Attenborough (a famous TV naturalist) pointing at a blue-footed booby bird and talking about it in his famous whispering voice! It's just an example. He could have simply said "The word naturalist makes me think of David Attenborough".
