DIScount CARD the idea

I do not know the name of the company but I read somewhere that it is coming out with a card that is giving discount to the LGBT community i.e. lesbian, gay, bisexual, transgenders people. One of the supporters of this said finally this community will have one reason to cheer that there are certain places friendly to them as well. It is hard to see any logic in this. If someone is really concerned about the community than he should take steps to represent their interests at a national level which would help them live a normal life as we do rather than subsidizing their food, clothes, and drink bills which will not serve any purpose. In fact, it will only lead to discount-induced purchases which in turn will lead to inflation!
The reason why I say this is because there is no way of verifying anyone’s sexual preferences. So even those who do not fall in this category but do not mind being considered a part of it will go for this card and avail of its benefits. This just looks as one of those marketing gimmicks by retailers to boost their sales and nothing else as somebody who is actually concerned about their well-being would take more concrete steps. One more way it will be misused is when the number of people holding such cards will be used to extrapolate the population of LGBT category.
