Views is starting to be an inaccurate term in some ways.
Sexed reality is framed as offensive as for example marching around an office loudly expressing a view that homosexuality is a sin.
In fact it is nearer religious tolerance. You cannot demand that everyone in your office prays with you, genuflects at your altar, and denounce them as sinners and try to get rid of them when they explain that no, they have other beliefs that they choose to live by. It is not 'offensive' to not believe what you do and live by those beliefs.
The issue is the demand to enable someone else's personal belief system and create it around them/reflect it back to them. Yes, that person may well perceive that as you rejecting the 'true authentic them' and other such stuff, but the distortion is there.
You are entitled to not be bullied or harassed for your beliefs and lifestyle if it is appropriate and within the boundaries of the situation you are in. Non participation and other beliefs to yours are not bullying or harassment. Failing to tolerate those with other beliefs and their boundaries and rights not to participate or enable you - and seeking to convert them, punish and coerce them into participation or get rid of them from your environment - is harassment.
