as strong as..

[bosun]

Can you please explain what the following sentence mean?( especially the red parts??)

We are only as strong or as weak as our relationships, so it does not make any sense to damage them. When dealing with friends and family, do I want to be right and weaker or agreeable and stronger?

[shalstudent]

We are only as strong or as weak as our relationships
If our relationship is strong, then we are strong. If our relationship is weak, then we are weak too.

Do I want to be right and weaker or agreeable and stronger?
What would I perefer? Being right and weak(maybe because there has been an arguement and we both don't seem to agree and I think that I am right) or

would I prefer to agree with the other party (my friend or family) and thus be strong (because our relationship is not damaged).
