I think the majority of people here have a blue avatar.
Not at all.
To illustrate my point:
Top 10 posters:
5 - Red (50%)
2 - Blue (20%)
2 - Constitution (20%)
1 - Green (10%)
Top 25 posters:
9 - Red (36%)
8 - Blue (32%)
4 - Independent (16%)
2 - Constitution (8%)
1 - Green (4%)
1 - Libertarian (4%)
Top 60 posters:
22 - Red (37%)
18 - Blue (30%)
7 - Independent (12%)
3 - Libertarian (5%)
3 - Constitution (5%)
3 - None (5%)
2 - Green (3%)
2 - Orange (3%)
Top 90 posters:
32 - Red
26 - Blue
15 - Independent
5 - Libertarian
4 - None
3 - Orange
3 - Constitution
2 - Green
Top 120 posters:
43 - Red
42 - Blue
17 - Independent
5 - Libertarian
4 - Orange
4 - None
3 - Constitution
2 - Green
So, no. If anything, Red avatars predominate, Blue avatars barely comprise 30% of the posters here.
