Can you post a copy/paste of the amendment in question so we all can peruse it. Thanks.
Neither the State of Colorado, through any of its branches or departments, nor any of its agencies, political subdivisions, municipalities or school districts, shall enact, adopt or enforce any statute, regulation, ordinance or policy whereby homosexual, lesbian or bisexual orientation, conduct, practices or relationships shall constitute or otherwise be the basis of or entitle any person or class of persons to have or claim any minority status, quota preferences, protected status or claim of discrimination. This Section of the Constitution shall be in all respects self-executing.
The part I put in bold is the problem, as I read Romer. You can deny special rights, but you cannot deny the fundamental right to Equal Protection under the Law. This Amendment would do precisely that.
