A non-Buddist paying respect to Guan Gong

Essentially the title says it all, I'm not a Buddist however I would like to pay my respects to Guan Gong known as the God of Warriors (although that's abit inaccurate) in the room I practice my Gung Fu. It's not used for anything else, so I wanted to put up some posters including one of Guan Gong (facing the door I believe or does that only go for shrines?).

Would this somehow be offensive?

Thanks.

Edit: I think I made a mistake, it should have been Taoism I believe, but the question remains the same for either.

How would it be offensive?

Google and Wikipedia are your friends, by the way.

Since it is generally held that all sentient beings possess Buddha nature I don't think it matters if you're Buddhist or not.

I did check out google/wikipedia but as it is written he is worshipped by 3 different religions none of which I'm apart of therefore I wasn't very sure, so I thought I'd ask more specifically.

Thanks for the reply.

I think a more proper question would be whether this collides with any religion you are a part of.

I think from a Buddhist perspective it may be more correct to say he is "revered" rather than "worshipped". I haven't looked it up, but I wouldn't be surprised to find out that he is unknown in the Japanese strains of Buddhism.

I'm a weak agnostic therefore I'm not apart of any major religion.

I see. Yes I've never actually heard of him mentioned in any Japanese context.
