I agree with others that when you create another protected group you just add to the backlog within the legal system. I think discrimination should just pertain to humans and their equal humane treatment, PERIOD.
I find it strange that discrimination is only considered in certain cases. The earlier study showed where EXXon was suspect, but as someone stated it could have been for completely unrelated reasons, yet they are labeled as discriminatory for this setup from a group with an agenda. Why is there no discrimination on race and sex, yet EEO quotas exists and this is not considered discrimination by law, why as you are telling the employer to hire the protected class for whatever reason??
As to the B&B owner that was sued and lost in the UK, why are the owners not allowed to choose whom to serve to? They admittedly also denied non-married heteros admittance as well, and this wasn't considered discrimination why (no one here is screaming about that injustice)? Or how about the store owners that discriminate against youth by not giving Senior discounts or limiting ordering from the Kid's menu, how is that not discrimination and allowed (as most businesses in the US adhere to such standards) when people not of a certain age get no perks?
Those types of cases never get taken and are frivolous, yet here in my hometown, a couple from a protected race have been denied a $300K business loan that they say will cost their business $50 million in revenue after they were told they were getting the loan. They are suing for discrimination (and more than likely the city will settle out of court rather than waste lawyer and courts expenses to fight this, as they are in negations as has been reported by the local news and city officials), yet the information not added to the public release was that they have a $1Million delinquency on their home loan that they failed to report in the loan documents, and their home was securing the loan. When this was found out, the loan was then denied. How is this discrimination? It is not but they are making headlines for their charges just as the EXXon story, where more may meet the eyes.
As to the religious ends, all I need say about that is refer to the religious zealots that picket the soldiers funerals and use their protections under the laws, Religions are no better in their addition to the lawsuit backlog.
The fact is that we are all different and there will never be true equality due to these differences. Don't think so try to go to most areas in the US, get a group of mixed individuals together, all take your shirts off and see if issues don't arise for the girls pertaining to nudity, public indecency, etc. Males have breasts just like women, but they are not considered taboo, even with sex being protected against discrimination, it is still allowed. Things won't generally change, just the court systems will be even more taxed with lawsuits in regard to the new law changes.
