I don't mind the odd cross fire on the bridge but chasing someone right back into their own base when attacking is truely a stupid thing to do. It just reminds me of g3er styles where the goal is to get as much frags as you can so you chase the 1st person you see....
I tend to try avoid chasers by blatently speed jumping around and if you chase a demoman you've got some problems
