Should congress pass an equal rights to amendment, to make everyone equal cause a problem

Answer:it will cause problems

I don't really see a need for the Equal Rights Amendment in the US constitution because all American citizens are already protected under the equal protection clause of the 14th Amendment. I suppose I see the reasoning that it would "make sure" that everyone is to be treated equally, but wouldn't it just be redundant to the 14th? Yes, I totally believe everyone should be treated equally, but is gender discrimination as big of an issue as it seems to be?
