I find that a bit difficult to believe and can't seem to find anything in the penal code about it. It seems to me that if someone is drunk that doesn't negate your right to defend yourself and yours.
I think you missed something in the Penal Code that might have answered your question. The Penal Code does not recognize intoxication as a defense, so it clearly would not affect your need to defend yourself.
8.04. INTOXICATION.  (a) Voluntary intoxication does 
not constitute a defense to the commission of crime.
	(b)  Evidence of temporary insanity caused by intoxication 
may be introduced by the actor in mitigation of the penalty attached 
to the offense for which he is being tried.
	(c)  When temporary insanity is relied upon as a defense and 
the evidence tends to show that such insanity was caused by 
intoxication, the court shall charge the jury in accordance with 
the provisions of this section.
	(d)  For purposes of this section "intoxication" means 
disturbance of mental or physical capacity resulting from the 
introduction of any substance into the body.
