This guy calls rainbow cakes 'gay cakes' - are we really in 2017?

Where's the eye-rolling emoji when you need one?

On Tuesday (May 30), irate netizen Peng Jia Rong (彭嘉荣) went on a tirade against rainbow cakes, and posted his rant on the "We are against Pinkdot in Singapore" Facebook group.

According to the post, he was at a "young punk" cafe in Singapore when he spotted a "rainbow cake".

Triggered by the multi-layered gateau, he wrote that "these are not rainbow cakes. (A) rainbow has 7 colours".

"These are gay cakes. Nothing wrong with a gay cake, sure, but please call a spade a spade. Stop covering up gay agenda. Now."

So if we're to follow his line of reasoning correctly, a rainbow has seven colours and this cake has six. The missing colour was not an "unknowing" mistake on the part of the baker.

Therefore, it's only logical that the six-coloured dessert he spotted supports what he calls the "gay agenda".

Well… there's a spurious argument if there ever was one.

Or is it?

An online media outlet suggested that Mr Peng might have likened the rainbow cake to the LGBT (lesbian, gay, bisexual, transgender) pride flag which also has six colours.

"The flag was designed with six colours after the assassination of San Francisco commissioner Harvey Milk so that an even number of colours could be distributed evenly between parade marchers as they demonstrated solidarity."

But the article conceded that Mr Peng's argument might be "stretching it" and the baker might have decided to combine indigo and violet into one layer for convenience sake.

Reactions to the original post have been a mix of hilarious and tongue-in-cheek.

Like-minded members of the group seem to support his dubious claim.

Others provided a more practical explanation of the six-layers.

Yet others have a more… specific preference.

In other pastry-related news, a pastor claimed an anointed cake magically "saved" a gay bartender.

Maybe Mr Peng will like that cake better.
