1.In almost every hindu temple, at the entrance to the temple, a signboard mentioning 'People of other religions are forbidden entry'.
2.On the contrary any Ram, Raheem or Robert can enter a church, partake in the sabbath services etc.
3.Ultimately it is acts demonstrating Love that draws people and not exclusivism nor grand eloquent discourses on philosophy or religion.
1. The nature of Hindu temples are different from that of Churches and masjids. Hindus believe in idol worship and temple is the place where they believe God's presence is felt. They pray before the God's deity/deities. In many temple there are many deities and people pray before all of them or some of them. Whereas Church is just a prayer house. People assemble there to just pray to their God. They are not considered as an abode of God in the form of a deity. This being the important difference, it is only fair that a person who enters the temple and goes before the deity and looks at it as a curio or an object of ignorance or pagan belief is kept away from there(good for him as well as for hindus). If you believe in idols worship, you can enter any Hindu temple claiming to be one-just a declaration is enough. You can go and pray before the deity. It is too simplistic an argument to give this as a reason for attraction/conversion to Abrahamic religions. Much more maturity is expected from the member who would argue on this line.
2. Already answered in 1 above. Ram, Rahim, Robert and a Bodhivarman and a Nimish jain too can enter a Hindu temple if he declares that he believes in the idol worship of Hindus. That moment he becomes a Hindu and he becomes eligible to enter the temple precincts.
3. Acts demonstrating love can be a) living a pure harmless life b)being compassionate to every life on earth c)being truthful and friendly to every one, extending help in whatever way one can to people in need etc., Without that wonderful thing called love none of this is really possible. Hindus do all this and more. When a hindu donates money to charity, he is least bothered about the beneficiary's religion. He just gives out of real compassion and forgets it.
4. Offering money to satisfy peoples' immediate needs by surreptitiously bringing it from abroad-from the donations of people with troubled consciences- (pledging in the process your culture, heritage and independence to the bloodied money), supplying tonnes and tonnes of milk powder (which is otherwise fed to pigs) and flooding selected schools with a surfeit of that supply, selectively offering scholarship with an undeclared quid pro quo in the background, conducting matrimony jihads by sending in dedicated jihadis for the purpose to ensnare girls from other faiths, can also be called "out of love and affection". But there is something called universal truth. How many of the ministries and churches are ready to open stalls in the prakArams of hindu temples(without going in because that would require accepting idol worship) and offer milk powder, ghee etc imported from Australia and US to the devotees thronging the temples without expecting any thing in return. Love can only be unconditional. It can never be conditional. If it is conditional it is not love. It is again another too simplistic an argument for the conversions.
5. You have come to a forum where the spiritual awareness level of the members are quite high. So there is no use complaining about eloquent discourses on philosophy or religion. That is the subject which is discussed by members here quite often. If you find it incomprehensible Latin or Afrikaans, keep away and do not participate. Do not trash the ideas discussed or the people discussing them. They are not fools. And I have visited some of the discussion forums of Christianity where there is a war going on about whether the God is Triune or one. There are arguments which trash the triune God (The Father , Son and the Holy Ghost) spoken about in the Bible. There are defenders too who take a leaf or two from Vaishnavism's diune God (Lakshmi and Narayana) and present verbatim arguments which they understand or not from Sri Vaishnavite Acharyas and Vedas. LOL.
