The point is not to be מקטרג on Jews chas vi-shalom but to be מעורר....
1] Splitting up a minyan so that two Aveilim get the amud.
2] Multiple Aveilim saying Kaddish together.
3] Women accompanying the מת to the מקום קבורה. [See שו"ע יו"ד שנ"ט].
4] All of the chatter at the Beis Aveil. [See יחזקאל כ"ד י"ז, the Gemaros that quote the pasuk in מועד קטן and the poskim].
5] All of the chatter in our culture in general [עי' הלכות דעות ב-ד].
6] Mishnayos shiur in the Beis Aveil [like between mincha and ma'ariv]. An Aveil is אסור בתלמוד תורה.
7] Hespedim given when Hespedim are forbidden [with the perfunctory preface that "we are not allowed to be Maspid but....". Sort of like "nisht Shabbos geredt - but how are your investments working out? Where do you think I should put my money?"].
8] Aveilim leaving the house during the shiva.
9] The insistence that the Aveil be served his food [this is only a din for the first seuda].
10] Aveilus means [acc. to Rambam] Teshuva.
טוֹב לָלֶכֶת אֶל בֵּית אֵבֶל מִלֶּכֶת אֶל בֵּית מִשְׁתֶּה בַּאֲשֶׁר הוּא סוֹף כָּל הָאָדָם וְהַחַי יִתֵּן אֶל לִבּוֹ.
Join the wave.
