I also don't like his administration forcing businesses to cater to same-sex couples when they choose not to do so (for instance, the wedding cake bakery in Denver). Any business should be allowed to be selective and to deny whom they serve, gay or straight, if they so desire.
Putting aside your stance on this issue, what did the Obama administration have to do with the wedding cake case in Denver? That had to do with Colorado's state anti-discrimination laws, not any policy that the Obama administration has ever pursued, so how on Earth is that an example of Obama's administration being a "catastrophe for our country?"
