Relationships at the Work place

So I just wanted to see how you guys feel about going after someone you know through the work place, and or dating someone that works at the same job as you. Is it hard to deal with it cause of the homosexual relationship? Cause honestly I see CIS co-workers dating each other and no one seems to care but once it's an LGBT couple it's a big deal.... With both groups in mind, I can see the break up hurting your job and or relationship with the company. But why make such a bigger deal when it's LGBT related. Like I get it being CIS is fucking boring but you don't have to make drama over something that has nothing to do with you.
