What about those things is undesirable? Leaving religion aside, it seems like all those (OpenOffice aside :) lead to a much happier state of mind than the alternative.
1. Automatically loving thy neighbour (ie. everyone) is a ridiculous notion. You love the people that are most important to you, that deserve your utmost respect and kindness, so of course this will mean you love a select few. Furthermore, trying to think up reasons why you should love any random neighbour would be an exhausting exercise in self-deception. Plus if you don't love people for their qualities, but instea…
To see that this is ridiculous, try substituting other emotions in for love: Happy thy neighbour, Angry thy neighbour, Sad thy neighbour.
In the phrase love is a solid verb. It is about taking the time to help the person out when they require external assistance.
Crawling out of bed at 3am to change the sheets after your kid pisses the bed -> Picking up an extra coffee at lunch for Bob at the office when he has had a ton of work dumped on him and can't get away from his desk.
Taking your spouse out to dinner to celebrate their new promotion -> Congratulating Sue from down the hall when her daughter makes the news for winning a spelling bee.
Picking up your brother from the airport -> Inviting the new guy over for a beer.
I would claim that all of these are loving actions but none of them require you to have exactly one special emotional state. Certainly, being dragged out of bed doesn't inspire much poetry at the time.
Further, none of these requires a specific justification beyond reducing human suffering/making the world a better place so you needn't exhaust yourself looking for reasons. And I certainly hope that welcoming the new guy without even knowing his qualities to judge him by doesn't devalue the act.
