I don't completely disagree with you about not everyone being brown, but comparing a photo of modern people to those 2000+ years ago is disingenuous. A lot has happened to the gene pool since, not to mention living conditions and skin protection have improved dramatically.

People just don't realize the actual history when they comment on stuff like this.

Like most people tend to disbelieve when they see redhead and fair skinned Lybian Bernbers that they represent an indigenous African population from pre-history (though technically there's evidence they came down from Europe during the tail end of the ice age).

In fact, Ramses II's forensic report from when they shipped his body to France for examination reported he had red hair and fair skin like a Lybian Berber (which is particularly interesting given the Greek story of Danaus, Lybian brother to the Pharoh who had 50 sons, given Ramses II also had 48-50 recorded sons).

The Mediterranean was much more of a giant melting pot than most people realize. Heck, it was more of a melting pot than most scholars realized given some of the surprises just in the past two years regarding genetic export from North Africa across much of the Mediterranean as opposed to the previous view of mostly import to North Africa from the Phonecians.

I'd recommend most people set aside their preconceptions, because relying on them will almost certainly lead to misinformed positions.
