Because it makes no difference. A negative vote of zero, or a negative vote of 99, or a negative vote EQUAL TO THE AFFIRMATIVE VOTE, is irrelevant to the calculation, if the calculation is based on "members present". Likewise for "total membership". - Taking the negative vote tells you nothing about the winning or losing margin. Thus, it is a waste of time. Thus, it is truly dilatory. (To repeat: If the calculation is based on "present and voting", then that is significantly different. -- The negative vote is to be counted, since it is one of the elements you must account for in your calcuation.) True. - But there are very few rules in Robert's Rules where Robert's Rules says "Don't do this". Page 390 gives two steps. Page 390 does not give two steps plus all the "not to do" things one would do for (a.) calculation based on "present and voting"; (b.) calculation based on "total membership". You can test this out. • Assume a rule which requires "a majority of those present." • Assume the total members PRESENT = 100. • This makes "51" the threshold for adoption since "a majority of 100" is 51. • Assume the vote is 10 affirmative. • Assume (for your sake) that the negative vote is taken, and the negative vote is 10. Q. Before you do a count of all members PRESENT, does the fact that the affirmative and negative are both the same value change the net result? Answer: No. If the affirmative were to be 2x more, and/or the negative were to be 2x less, OR VICE VERSA, it makes not a whit of difference in the final calculation. E.g., 20 ayes and 5 noes = no difference. E.g., 5 ayes and 20 noes = no difference. • Now do the calculation: 10 affirmative; 100 present; 10 is SHORT of "a majority of those present" (note: 51 is a majority of 100). Thus, the motion is rejected. Q. Does the fact that the negative is GREATER THAN or LESSER THAN the number of affirmative votes alter the result? A. No. Whatever number the negative vote turns out to be, EVEN IF GREATER THAN THE AFFIRMATIVE, is irrelevant to the calculation. Your step #3 is not taken from page 390. Your step #4 isn't taken from anywhere (i.e., you don't announce the negative vote when the vote threshold is based on "members present"). Per page 390, (a.) you don't take the negative vote; (b.) you don't announce the negative vote. The negative vote quantity is meaningless because it is never used in the calculation.
