[kozak_]

You have the right to use coarse language, but if you take advantage of that right in some businesses, they reserve the right to ask you to leave.

Same thing here, you have the right to pick your sexual orientation, but this law codifies the right of the business to say "we reserve the right to not serve you because it deeply offends us".

You might not agree with them but understand that for some folks and the deeply religious, this goes against their conscience and against their beliefs. This law is meant to allow them to say "NO".
