Vehemence, to me, incorporates passion,strength, power and more.
I'm attracted to strong images when I paint.
I'd rather have a strong reaction to something or someone then be indifferent....would I rather someone felt the same way about me????
I love the word vehemence - how it sounds when you say it out aloud (are you doing that now?)
All this said, I also value being gentle, kind and nice. Qualities such as these are not the antithesis of vehemence. They can exist side by side.
It's all about balance.....
