I wouldn't go so far as to say it's offensive, but I can agree it's disrespectful. Respect is shown by the lengths someone goes through to demonstrate someone/ something is important and held in high regard.

Examples:

When you are talking to someone you respect, you demonstrate it by making a point to convey that you are listening to them and thinking about what they are saying.

When a tragedy happens, we often show respect by holding a moment of silence where we interrupt whatever we are doing to hold a moment to think about the victims.

Similarly, a traditional way of demonstrating respect for people's contributions in a given field is through an awards ceremony where attendees both given their attention and dress in formal attire to mark the significance and importance of the event.

It’s not my job to educate you or teach you manners or how to live in a society. How can I explain all that in a chat reply when you’re clearly ignorant and weren’t raised right. I can’t fix you dude
