Hmmm I play Rugby and my team mates will ask if I am playing football next saturday, they mean rugby but DO call it football. I also play 'football' - I am probably better at soccer than Rubgy(football) but prefer rugby because it's a better team game - I play soccer on sunday for a team and Weds in a 5-a-side league and monday for fun/fitness training so I do know what I am talking about 😛
In rugby union we kick probably as much as Aussie rules and nearly as much as Gaelic, so if you do not wish to call rubgy football then you should not allow these other 2 to be done so - all in all they are ALL football of a differing code. If there was no kicking it would be Handball, which is an official sport with goals, or basketball etc.
